Merge branch 'drm-next-4.7' of git://people.freedesktop.org/~agd5f/linux into drm-next

This is the first big radeon/amdgpu pull request for 4.7.  Highlights:
    - Polaris support in amdgpu
      Current display stack on par with other asics, for advanced features DAL is required
      Power management support
      Support for GFX, Compute, SDMA, UVD, VCE
    - VCE and UVD init/fini cleanup in radeon
    - GPUVM improvements
    - Scheduler improvements
    - Clockgating improvements
    - Powerplay improvements
    - TTM changes to support driver specific LRU update mechanism
    - Radeon support for new Mesa features
    - ASYNC pageflip support for radeon
    - Lots of bug fixes and code cleanups
