Add a PCI power control driver that's capable of correctly powering up
devices using the power sequencing subsystem. The first users of this
driver are the ath11k module on QCA6390 and ath12k on WCN7850. These
packages require a certain delay between enabling the Bluetooth and WLAN
modules and the power sequencing subsystem takes care of it behind the
scenes.

Some PCI devices must be powered-on before they can be detected on the
bus. Introduce a simple framework reusing the existing PCI OF
infrastructure.
The way this works is: a DT node representing a PCI device connected to
the port can be matched against its power control platform driver. If
the match succeeds, the driver is responsible for powering-up the device
and calling pci_pwrctl_device_set_ready() which will trigger a PCI bus
rescan as well as subscribe to PCI bus notifications.
When the device is detected and created, we'll make it consume the same
DT node that the platform device did. When the device is bound, we'll
create a device link between it and the parent power control device.

We are reusing the platform bus as it provides us with all the

With PCI power control we deal with two struct device objects bound to
two different drivers but consuming the same OF node. We must not bind
the pinctrl twice. To that end: before setting the OF node of the newly
instantiated PCI device, check if a platform device consuming the same
OF node doesn't already exist on the platform bus and - if so - mark the
PCI device as reusing the OF node.

Using 0x82 seems odd, where everything else is just a sequence.
On E850, this macro isn't used (as a register value), only to assign
its value to the 'extrefclk' variable, which is otherwise unused on
that platform. Older platforms don't appear to support 26MHz in the
first place (since this macro was added for E850).
Furthermore, the downstream driver uses 0x82 to denote
USBPHY_REFCLK_DIFF_26MHZ (whatever that means exactly), but for all the
other values we match downstream's non-DIFF macros.

When EMLSR gets unblocked, the current code checks if the last exit was
due to an EXIT reason (as opposed to a BLOCKING one), and if so, it
does nothing, as in this case a MLO scan was scheduled to run in 30
seconds.
But the code doesn't consider the time that passed from the last exit,
so if immediately after the exit a blocker occurred (e.g. non-BSS
interface), and lasts for more than 30 seconds, then the MLO scan and the
following link selection will decide not to enter EMLSR, and when the
unblocking event finally happens, the reason is still set to the EXIT one,
so it will do nothing, and we will not have the chance to re-enable EMLSR.
Fix this by checking also the time that has passed since the last exit,
only if it is less than 30 seconds, we can count on the scheduled MLO
scan.
Note that clearing the reason itself can't be done since it is needed
for the EMLSR prevention mechanism.

When e.g. wpa_supplicant sets only the MLD "sta" authorized
state, the code actually applies that change, but then returns
an error to userspace anyway because there were no changes to
the link station, and no link ID was given. However, it's not
incorrect to not have a link ID when wanting to change only
the MLD peer ("sta") state, so the code shouldn't require it.
To fix this, separate the "new_link" argument out into a new
three-state enum, because if modify is called on a link STA
only, it should return an error if no link is given or if it
doesn't exist. For modify on the MLD "sta", not having a link
ID is OK, but if there is one it should be validated.
This seems to not have mattered much as wpa_supplicant just
prints a message and continues, and the authorized state was
already set before this error return. However, in the later
code powersave recalculation etc. will be skipped, so that it
may result in never allowing powersave on MLO connections.

Currently NL80211_RATE_INFO_HE_RU_ALLOC_2x996 is not handled in
cfg80211_calculate_bitrate_he(), leading to below warning:
kernel: invalid HE MCS: bw:6, ru:6
kernel: WARNING: CPU: 0 PID: 2312 at net/wireless/util.c:1501 cfg80211_calculate_bitrate_he+0x22b/0x270 [cfg80211]
Fix it by handling 2x996 RU allocation in the same way as 160 MHz bandwidth.

Commit 3e2f544dd8 ("net: get stats64 if device if driver is
configured") moved the callback to dev_get_tstats64() to net core, so,
unless the driver is doing some custom stats collection, it does not
need to set .ndo_get_stats64.
Since this driver is now relying in NETDEV_PCPU_STAT_TSTATS, then, it
doesn't need to set the dev_get_tstats64() generic .ndo_get_stats64
function pointer.
In this driver specifically, .ndo_get_stats64 basically points to
dev_fetch_sw_netstats(). Now it will point to dev_get_tstats64(), which
calls netdev_stats_to_stats64() and dev_fetch_sw_netstats().
netdev_stats_to_stats64() seems irrelevant for this driver.

With commit 34d21de99c ("net: Move {l,t,d}stats allocation to core and
convert veth & vrf"), stats allocation could be done on net core instead
of this driver.
With this new approach, the driver doesn't have to bother with error
handling (allocation failure checking, making sure free happens in the
right spot, etc). This is core responsibility now.
Move mac80211 driver to leverage the core allocation.

Jiazi Li reported that they occasionally see hash table duplicates
as evidenced by the WARN_ON() in rb_insert_bss() in this code. It
isn't clear how that happens, nor have I been able to reproduce it,
but if it does happen, the kernel crashes later, when it tries to
unhash the entry that's now not hashed.
Try to make this situation more survivable by removing the BSS from
the list(s) as well, that way it's fully leaked here (as had been
the intent in the hash insert error path), and no longer reachable
through the list(s) so it shouldn't be unhashed again later.

When a monitor interface is started, ieee80211_recalc_offload() is
called and 802.11 encapsulation offloading support get disabled so
monitor interface could get native wifi frames directly. But when
this interface is stopped there is no need to keep the 802.11
encpasulation offloading off.
This call ieee80211_recalc_offload() when monitor interface is stopped
so 802.11 encapsulation offloading gets re-activated if possible.

For the EHT EIRP transmit power envelope, the 320 MHz is in
the last octet, but if we've copied 4 octets (count == 3),
the next one is at index 4 not 5 (count + 2). Fix this, and
just hardcode the offset since count is always 3 here.

The control and ack force-wake registers are not accessible for
the VF drivers. To avoid changing existing code logic that tracks
woken domains, simply ignore all attempts to access control or ack
registers if we are running as a VF driver.

For debug purposes it might be useful to look at the values of the
force-wake ack registers in case wake/sleep operations failures.
Move xe_gt_notice() from the caller to the helper function, where
we have the latest value of force-wake ack register available.
