drm/i915/psr: Do not wait for PSR being idle on on Panel Replay

Browse source

We do not have ALPM on DP Panel Replay. Due to this SRD_STATUS[SRD State]
doesn't change from SRDENT_ON after Panel Replay is enabled until it gets
disabled.

On eDP Panel Replay DEEP_SLEEP is not reached.
_psr2_ready_for_pipe_update_locked is waiting DEEP_SLEEP bit getting reset.

Take these into account in Panel Replay code by not waiting PSR getting
idle after enabling VBI.
