Merge branch 'drm-next-4.9' of git://people.freedesktop.org/~agd5f/linux into drm-next

More radeon and amdgpu changes for 4.9. Highlights:
- Initial SI support for amdgpu (controlled by a Kconfig option)
- misc ttm cleanups
- runtimepm fixes
- S3/S4 fixes
- power improvements
- lots of code cleanups and optimizations
