drm/i915/psr: Do not write registers/bits not applicable for panel replay

drm/i915/psr: Do not write registers/bits not applicable for panel replay

Bspec is saying this
mask register: Only PSR_MASK[Mask FBC modify] and PSR_MASK[Mask Hotplug]
are used in panel replay mode.

Status register: Only SRD_STATUS[SRD state] field is used in panel replay
mode.

Due to this stop writing and reading registers and bits not used by panel
replay if panel replay is used.

Bspec: 53370, 68920

v2:
  - use intel_dp_is_edp with PSR_MASK register
  - handle LunarLake as well
  - hanle ALPM configuration as well
