Merge branch 'drm-next-4.13' of git://people.freedesktop.org/~agd5f/linux into drm-next

New radeon and amdgpu features for 4.13:
- Lots of Vega10 bug fixes
- Preliminary Raven support
- KIQ support for compute rings
- MEC queue management rework from Andres
- Audio support for DCE6
- SR-IOV improvements
- Improved module parameters for controlling radeon vs amdgpu support
  for SI and CIK
- Bug fixes
- General code cleanups

[airlied: dropped drmP.h header from one file was needed and build broke]
