Merge tag 'drm-intel-next-2017-07-17' of git://anongit.freedesktop.org/git/drm-intel into drm-next

2nd round of 4.14 features:

- prep for deferred fbdev setup
- refactor fixed 16.16 computations and skl+ wm code (Mahesh Kumar)
- more cnl paches (Rodrigo, Imre et al)
- tighten context cleanup and handling (Chris Wilson)
- fix interlaced handling on skl+ (Mahesh Kumar)
- small bits as usual
