Merge branch 'drm-fixes-4.7' of git://people.freedesktop.org/~agd5f/linux into drm-fixesdrm-fixes-for-v4.7-rc4

radeon and amdgpu fixes for 4.7.  Highlights:
- fixes for GPU VM passthrough
- fixes for powerplay on Polaris GPUs
- pll fixes for rs780/880

* 'drm-fixes-4.7' of git://people.freedesktop.org/~agd5f/linux:
  drm/amd/powerplay: select samu dpm 0 as boot level on polaris.
  drm/amd/powerplay: update powerplay table parsing
  Revert "drm/amdgpu: add pipeline sync while vmid switch in same ctx"
  drm/amdgpu/gfx7: fix broken condition check
  drm/radeon: fix asic initialization for virtualized environments
  amdgpu: fix asic initialization for virtualized environments (v2)
  drm/radeon: don't use fractional dividers on RS[78]80 if SS is enabled
  drm/radeon: do not hard reset GPU while freezing on r600/r700 family
