drm/i915/psr: Panel replay uses SRD_STATUS to track it's status

Browse source 
DP Panel replay uses SRD_STATUS to track it's status despite selective
update mode.

Bspec: 53370, 68920

v4:
  - use PSR2_STATUS for eDP Panel Replay
  - handle intel_psr_wait_exit_locked as well
v3:
  - do not use PSR2_STATUS for PSR1
v2:
  - use intel_dp_is_edp to differentiate
  - modify debugfs status as well
