Pull drm fixes from Dave Airlie:
 "Weekly fixes pull.

  This contains some fixes for sun4i/dw-hdmi probing, then amdgpu
  enables arcturus hw without experimental flag and two other fixes and
  a group of i915 fixes.

  It also has a backported from next fix for the warn on reported in
  ast/drm_gem_vram_helper code in the merge window. There's a separate
  report which initially looked to be the same problem, but I'm going to
  chase that up next week a bit more as I don't think the bisect landed
  anywhere useful.

  Summary:

  core:
   - vram helper TTM regression fix

  amdgpu:
   - Pageflip fix for navi1x with 5 or 6 displays
   - Remove experimental flag for Arcturus
   - Fix regression in atomic commit tail rework

  i915:
   - Fix tgl power gating issue
   - Memory leak fixes
   - Selftest fixes
   - Display bpc fix
   - Fix TGL MOCS for PTE tracking

  dw-hdmi:
   - probing fix

  sun4i:
   - probing fix"
