Extend the page fault action INI to handle following:
1) Ignore page fault event
2) Trigger SSR on page fault threshold
3) Send blob of data to userspace on page fault threshold
On pagefault wakeup event, save per symbol pagefault timestamp
and once the event count reaches configured threshold within the
configured time interval, either trigger SSR or notify userspace
with pagefault address and count based on INI configuration.

Currently, userspace sends
"QCA_NL80211_VENDOR_SUBCMD_SET_WIFI_CONFIGURATION" vendor command
for power configuration. With this vendor command, driver receives
the PS parameters which it sends it to the target. Usually,
inactivity timeout is 200ms, but in some scenario, if driver send
the inactivity timeout as zero, then it causes crash in target as
target expects non-zero value.
Scenarios:
1. Userspace updates inactivity timeout to zero.
2. For OPM mode as disable(0) or enable(1), driver updates the PS
params to zero. So, inactivity timeout is zero.
So, to fix this, return invalid if userspace send ITO value as zero
and update vdev PS params for OPM mode as user defined(2).

According to new requirement, add INIs
max_pagefault_wakeups_for_ssr,
interval_for_pagefault_wakeup_counts and
ssr_frequency_on_pagefault to trigger SSR if host wakes up
because of pagefault.
For ex: If max_pagefault_wakeups_for_ssr = 30,
interval_for_pagefault_wakeup_counts = 180000 (3 mins) and
ssr_frequency_on_pagefault = 3600000 (1hr), in this case host
will trigger the SSR if it receives 30 wakeups because of
pagefaults in 3 mins, host will trigger SSR only once in 1 hr.
Once the SSR is triggered, host will not trigger next SSR for
next 1 hr even if it receives 30 wakeups from fw because of pagefaults.
This 1 hr time is getting monitored from last SSR.

Currently general PM delay is 500 ms. If fw sends wow wakeup with reason
code WOW_REASON_LOCAL_DATA_UC_DROP host wakes up, 500 ms after the

wake there will be a small delay induced. It is noticed that large

To address this issue increase PM delay to 1200 ms if fw sends

revert it back to 500 ms on next WoW enter.
