drm/i915/psr: Allow changing Panel Replay mode without full modeset

Browse source

Currently we are forcing full modeset if Panel Replay mode is changed. This
is not necessary as long as we are not changing sink PANEL REPLAY ENABLE
bit in PANEL REPLAY ENABLE AND CONFIGURATION 1 register. This can be
achieved by entering Panel Replay inactive mode (Live Frame mode) when
Panel Replay is disabled and keep PANEL REPLAY ENABLE bit in PANEL REPLAY
ENABLE AND CONFIGURATION 1 enabled always if panel is just supporting Panel
Replay.
