Merge branch 'drm-next-4.2-amdgpu' of git://people.freedesktop.org/~a…

…gd5f/linux into drm-next

This is the big pull request for amdgpu, the new driver for VI+ AMD
asics.  I currently supports Tonga, Iceland, and Carrizo and also
contains a Kconfig option to build support for CI parts for testing.

All major functionality is supported (displays, gfx, compute, dma,
video decode/encode, etc.).  Power management is working on Carrizo,
but is still being worked on for Tonga and Iceland.
