[PATCH v5 12/19] drm/i915/psr: Perfrom psr2 checks related to ALPM for Panel Replay

[Jouni Högander]

eDP1.5 support ALPM with Panel Replay as well. We need to check ALPM
related things for Panel Replay as well.

Bspec: 68920

v2: do not move Vblank >= PSR2_CTL Block Count Number maximum line count
    check
