Merge branch 'drm-next-4.6' of git://people.freedesktop.org/~agd5f/linux into drm-next

Browse Source 
First radeon and amdgpu pull request for 4.6.  Highlights:
- ACP support for APUs with i2s audio
- CS ioctl optimizations
- GPU scheduler optimizations
- GPUVM optimizations
- Initial GPU reset support (not enabled yet)
- New powerplay sysfs interface for manually selecting clocks
- Powerplay fixes
- Virtualization fixes
- Removal of hw semaphore support
- Lots of other misc fixes and cleanups
