Pull drm fixes fr9om Dave Airlie:
 "Fixes for amdgpu, and a bunch of arm drivers.

  There seems to be an uptick in the ARM drivers sending things for
  fixes which is good, so I've decided to dequeue a bit early, more
  stuff may arrive before the weekend.

  This contains mediatek, arcpgu, sunxi, fsl-dcu display controller
  fixes along with 3 amdgpu fixes, one for a fencing issue with
  secondary GPUs"
