Merge tag 'drm-intel-next-2016-09-19' of git://anongit.freedesktop.org/drm-intel into drm-next

- refactor the sseu code (Imre)
- refine guc dmesg output (Dave Gordon)
- more vgpu work
- more skl wm fixes (Lyude)
- refactor dpll code in prep for upfront link training (Jim Bride et al)
- consolidate all platform feature checks into intel_device_info (Carlos Santa)
- refactor elsp/execlist submission as prep for re-submission after hang
  recovery and eventually scheduling (Chris Wilson)
- allow synchronous gpu reset handling, to remove tricky/impossible/fragile
  error recovery code (Chris Wilson)
- prep work for nonblocking (execlist) submission, using fences to track
  depencies and drive elsp submission (Chris Wilson)
- partial error recover/resubmission of non-guilty batches after hangs (Chris Wilson)
- full dma-buf implicit fencing support (Chris Wilson)
- dp link training fixes (Jim, Dhinkaran, Navare, ...)
- obey dp branch device pixel rate/bpc/clock limits (Mika Kahola), needed for
  many vga dongles
- bunch of small cleanups and polish all over, as usual
