Merge tag 'drm-intel-next-2015-03-13-merge' of git://anongit.freedesktop.org/drm-intel into drm-next

drm-intel-next-2015-03-13-rebased:
- EU count report param for gen9+ (Jeff McGee)
- piles of pll/wm/... fixes for chv, finally out of preliminary hw support
  (Ville, Vijay)
- gen9 rps support from Akash
- more work to move towards atomic from Matt, Ander and others
- runtime pm support for skl (Damien)
- edp1.4 intermediate link clock support (Sonika)
- use frontbuffer tracking for fbc (Paulo)
- remove ilk rc6 (John Harrison)
- a bunch of smaller things and fixes all over

Includes backmerge because git rerere couldn't keep up any more.
