Merge branch 'drm-next-4.12' of git://people.freedesktop.org/~agd5f/linux into drm-next

Fixes for 4.12.  This is a bit bigger than usual since it's 3 weeks
worth of fixes and most of these changes are for vega10 which is
new for 4.12 and still in a fair amount of flux.  It looks like
you missed my last pull request, so those patches are included here
as well.  Highlights:
- Lots of vega10 fixes
- Fix interruptable wait mixup
- Fan control method fixes
- Misc display fixes for radeon and amdgpu
- Misc bug fixes
