qcacld-3.0: Add INIs to trigger SSR for wakeup on pagefault

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.
