Pull drm fixes from Dave Airlie:
 "The regular fixes pull for rc3. The i915 team found some fixes they
  (or I) missed for rc1, which is why this is a bit bigger than usual,
  otherwise there is a single amdgpu fix, some spi panel aliases, and a
  bridge fix.

  i915:
   - execlist access fixes
   - list deletion fix
   - CML display fix
   - HSW workaround extension to GT2
   - chicken bit whitelist
   - GGTT resume issue
   - SKL GPU hangs for Vulkan compute

  amdgpu:
   - memory leak fix

  panel:
   - spi aliases

  tc358767:
   - bridge artifacts fix"
