Pull drm fixes from Dave Airlie:
 "Nothing too unusual here for rc2. Except the amdgpu DMCU firmware
  loading fix caused build breakage with a different set of Kconfig
  options. I've just reverted it for now until the AMD folks can rewrite
  it to avoid that problem.

  i915:
   - boosting fix
   - bump ready task fixes
   - GVT - reset fix, error return, TRTT handling fix

  amdgpu:
   - DMCU firmware loading fix
   - Polaris 10 pci id for kfd
   - picasso screen corruption fix
   - SR-IOV fixes
   - vega driver reload fixes
   - SMU locking fix
   - compute profile fix for kfd

  vmwgfx:
   - integer overflow fixes
   - dma sg fix

  sun4i:
   - HDMI phy fixes

  gma500:
   - LVDS detection fix

  panfrost:
   - devfreq selection fix"
