Pull drm fixes from Dave Airlie:
 "First round of fixes for -rc1. I'll follow this up with the msm new hw
  support pull request.

  This just has three sets of fixes, some for msm before the new hw, a
  bunch of AMD fixes (includiing some required firmware changes for new
  hw), and a set of i915 (+gvt) fixes"
