Panel Replay is a power saving feature for DP 2.0 monitor and similar
to PSR on EDP.

These patches are basic enablement patches added on top of
existing psr framework to enable full-screen live active frame
update mode of panel replay. Panel replay also can be enabled
in selective update mode which will be enabled in a incremental
approach.

Note: The patches are not tested due to unavailability of monitorPanel replay phase1 implementation
