Pull drm fixes from Dave Airlie:
 "i915 fixes + 2 mediatek regressions.

  So some i915 fixes came in which I thought they might so I'm sending
  those along with two reverts for two patches to the mediatek driver
  that didn't seem to build so well, I've fixed up my -fixes ARM build
  and .config so I could see it, but yes brown paper bag time"
