drm/i915/psr: Detect panel replay selective update support
Add new boolean to store panel replay selective update support of sink into
intel_psr struct. Detect panel replay selective update support and store
it into this new boolean.
v3: Clear sink_panel_replay_su_support in intel_dp_detect
v2: Merge adding new boolean into this patch
