This patch introduces exit/activate functions for PSR
on VLV+. Since on VLV+ HW cannot track frame updates and force PSR
exit let's use fully SW tracking available.
v2: Rebase over intel_psr.c;
Remove Single Frame update transitioning from state 3 to 5 directly;
Fake a software invalidation for sprites and cursor so we don't miss
any screen update;
v3: As pointed out by Durgadoss msecs_to_jiffies used on wait_for only uses int,
so let's use 1 instead. Althought the 1/4 of this is needed for the
transition let's use 1 for simplicity;
Also fix comments as suggested by Durgadoss
