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
transactions again runtime suspend takes effect. Every time FW sends wow
wake there will be a small delay induced. It is noticed that large
frames are getting dropped for continuous wow wakeup events.
To address this issue increase PM delay to 1200 ms if fw sends
wow wake for reason WOW_REASON_LOCAL_DATA_UC_DROP and again
revert it back to 500 ms on next WoW enter.

This re-introduces the orignal patch which shutdowns WLAN in system
suspend prepare.
Orignal patch Id1f5172a7fc1792c83c8c1c20127de815f7e4980 is reverted by
Ic82db9dc0ca9d6686df99926335af27abc61cdb5 for deadlock issue.
However, deadlock between cnss_pm_notify and unregister_pm_notifier is
not caused by Id1f5172a7fc1792c83c8c1c20127de815f7e4980. So restore it
and add flag to enable/disable feature shutdown wlan in system suspend.
Deadlock issue is caused by "up_write(&cnss_pm_sem) is invoked before
down_write(&cnss_pm_sem) in function cnss_pm_notify". The issue can be
fixed by changes I533c373b85f554fbcceb562d9f56c6b88e5155bb and

To support shutdown WLAN when system goes into suspend, add idle shutdown

Before suspend/shutdown, user space should stop adapter. And after resume,
user space should restart adapter. This can ensure user and kernel space

configuration to enable/disable ARP/NS offload on fly.

such ARP/NS packet in the front, so prevent runtime suspend happen
if disable ARP/NS offload. System suspend still allow in consideration

It only support on STA/P2P-Client mode device, and this configure is
optional, while default behavior is ARP/NS offload enable. It will
