[PATCH v5 0/6] Panel replay phase1 implementation

[Animesh Manna]

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.

As per current design panel replay priority is higher than psr.
intel_dp->psr.panel_replay_enabled flag indicate panel replay is enabled.
intel_dp->psr.panel_replay_enabled + intel_dp->psr.psr2_enabled indicates
panel replay is enabled in selective update mode.
intel_dp->psr.panel_replay_enabled + intel_dp->psr.psr2_enabled +
intel_psr.selective_fetch enabled indicates panel replay is
enabled in selective update mode with selective fetch.
PSR replated flags remain same like before.

Note: The patches are under testing by using panel replay emulator and
panel is not avalible.
