Merge branch 'drm-intel-next' of git://people.freedesktop.org/~danvet/drm-intel into drm-next

New feature pile for 3.12! Highlights:
- Stereo/3d support for hdmi from Damien, both the drm core bits and
  the i915 integration.
- Manual boost/deboost logic for gpu turbo (Chris)
- Fixed up clock readout support for vlv (Chris).
- Tons of little fixes and improvements for vlv in general (Chon Minng
  Lee and Jesse Barnes).
- Power well support for the legacy vga plane (Ville).
- DP impromevents from Jani.
- Improvements to the Haswell modeset sequence (Ville+Paulo).
- Haswell DDI improvements, using the VBT for some tuning values and
  to check the configuration (Paulo).
- Tons of other small improvements and fixups.
