Check if requested segments ('segs' or 'ERST_DEFAULT_SEGS') exceeds the
maximum amount ERST supports.
When 'segs' is '0', 'ERST_DEFAULT_SEGS' is used instead. But both values
may not exceed ERST max.
Macro 'ERST_MAX_SEGS' is renamed to 'ERST_DEFAULT_SEGS'. The new name
better represents the macros, which is the number of Event Ring segments
to allocate, when the amount is not specified.
Additionally, rename and change xhci_create_secondary_interrupter()'s
argument 'int num_segs' to 'unsigned int segs'. This makes it the same
as its counter part in xhci_alloc_interrupter().
Fixes: c99b38c412 ("xhci: add support to allocate several interrupters")

Port capability flags for USB2 ports have been cached in an
u32 xhci->ext_caps[] array long before the driver had struct xhci_port
and struct xhci_port_cap structures.
Move these cached USB2 port capability values together with the other
port capability values into struct xhci_port_cap cability structure.
This also gets rid of the cumbersome way of mapping port to USB2
capability based on portnum as each port has a pointer to its capability
structure.

========
- Added a new API mhi_power_down_keep_dev() to not destroy the struct dev
associated with the MHI channels during MHI power down. This is useful in
scenarios such as system suspend/hibernation where the probability of
channels coming back is very high. So the PM maintainer suggested not to
destroy the struct dev in those cases.
This API is introduced for fixing the failure reported in the ath11k driver
during resume from system suspend.
NOTE: Due to the API dependency, the patch adding the API is pushed to an
immutable branch (mhi-immutable) and merged into both mhi and ath trees. But
the merge commit is not visible in mhi tree due to git being smart with
'fast-forward'.
- Added an optional sysfs entry to force the MHI devices to enter the Emergency
Download (EDL) mode to download the firmware from host.
- Added EDL mode support for Qcom SDX75/65/55 modems as per the MHI spec v1.2,
Chapter 13.2. This involves writing a cookie to the EDL doorbell registers and
then triggering the device reset from host.

A group of counters called "sysfs" displays software
C-state request counts and resulting perceived C-state residency.
They are not built-in counters that turbostat knows about ahead of time,
rather they are discovered in sysfs when turbostat starts.
Thus, they are added dynamically, using the same interface
as user-added MSR counters.
When turbostat enters "no-msr" mode, such as when running as a
non-privileged user, it clears all added counters.
Updating that to clear only actual MSR added counters
allows regular users to see the sysfs counters.
