[Intel-gfx] [PATCH 01/12] drm/i915/psr: Unify PSR pre/post plane update hooks

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

intel_psr_pre_plane_update() operates on a per-crtc level, whereas
intel_psr_post_plane_update() operates on the whole atomic commit,
for no real reason that I can see. Adjust intel_psr_post_plane_update()
to match the intel_psr_pre_plane_update() approach.
