Another day; another DSDT bug we need to workaround...
Since commit ca876c7483 ("gpiolib-acpi: make sure we trigger edge events
at least once on boot") we call _AEI edge handlers at boot.
In some rare cases this causes problems. One example of this is the Minix
Neo Z83-4 mini PC, this device has a clear DSDT bug where it has some copy
and pasted code for dealing with Micro USB-B connector host/device role
switching, while the mini PC does not even have a micro-USB connector.
This code, which should not be there, messes with the DDC data pin from
the HDMI connector (switching it to GPIO mode) breaking HDMI support.
To avoid problems like this, this commit adds a new
gpiolib_acpi.run_edge_events_on_boot kernel commandline option, which
allows disabling the running of _AEI edge event handlers at boot.
The default value is -1/auto which uses a DMI based blacklist, the initial
version of this blacklist contains the Neo Z83-4 fixing the HDMI breakage.

Currently frame registrations are not purged, even when changing the
interface type. This can lead to potentially weird situations where
frames possibly not allowed on a given interface type remain registered
due to the type switching happening after registration.
The kernel currently relies on userspace apps to actually purge the
registrations themselves, this is not something that the kernel should
rely on.
Add a call to cfg80211_mlme_purge_registrations() to forcefully remove
any registrations left over prior to switching the iftype.

When we expire an inactive station, try to send it a deauth. This
helps if it's actually still around, and just has issues with
beacon distribution (or we do), and it will not also remove us.
Then, if we have shared state, this may not be reset properly,
causing problems; for example, we saw a case where aggregation
sessions weren't removed properly (due to the TX start being
offloaded to firmware and it relying on deauth for stop), causing
a lot of traffic to get lost due to the SN reset after remove/add
of the peer.

In case we got a fw restart while roaming from encrypted AP to
non-encrypted one, we might end up with hitting a warning on the pending
counter crypto_tx_tailroom_pending_dec having a non-zero value.
The following comment taken from net/mac80211/key.c explains the rational
for the delayed tailroom needed:
/*
* The reason for the delayed tailroom needed decrementing is to
* make roaming faster: during roaming, all keys are first deleted
* and then new keys are installed. The first new key causes the
* crypto_tx_tailroom_needed_cnt to go from 0 to 1, which invokes
* the cost of synchronize_net() (which can be slow). Avoid this
* by deferring the crypto_tx_tailroom_needed_cnt decrementing on
* key removal for a while, so if we roam the value is larger than
* zero and no 0->1 transition happens.
*
* The cost is that if the AP switching was from an AP with keys
* to one without, we still allocate tailroom while it would no
* longer be needed. However, in the typical (fast) roaming case
* within an ESS this usually won't happen.
*/
The next flow lead to the warning eventually reported as a bug:
1. Disconnect from encrypted AP
2. Set crypto_tx_tailroom_pending_dec = 1 for the key
3. Schedule work
4. Reconnect to non-encrypted AP
5. Add a new key, setting the tailroom counter = 1
6. Got FW restart while pending counter is set ---> hit the warning
While on it, the ieee80211_reset_crypto_tx_tailroom() func was merged into
its single caller ieee80211_reenable_keys (previously called
ieee80211_enable_keys). Also, we reset the crypto_tx_tailroom_pending_dec
and remove the counters warning as we just reset both.

When the RFKILL subsystem isn't available, then rfkill_blocked()
always returns false. In the case of hardware rfkill this will
be wrong though, as if the hardware reported being killed then
it cannot operate any longer.
Since we only ever call the rfkill_sync work in this case, just
rename it to rfkill_block and always pass "true" for the blocked
parameter, rather than passing rfkill_blocked().
We rely on the underlying driver to still reject any new attempt
to bring up the device by itself.
