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

Fix a bunch of VRR problems:
- inconsistent register latch point on icl/tgl
- bogus guardband/vblank exit length calculations on adl+
- adjustments to the vrr enable/disable seqeuence to avoid
  pipe/transcoder getting stuck on mtl when switching from
  vrr mode to non-vrr mode

Ville Syrjälä (4):
  drm/i915/vrr: Make registers latch in a consitent place on icl/tgl
  drm/i915/vrr: Fix guardband/vblank exit length calculation for adl+
  drm/i915/vrr: Reorder transcoder vs. vrr enable/disable
  drm/i915/vrr: Be more careful with the bits in TRANS_VRR_CTL
