Merge tag 'drm-intel-fixes-2015-08-20' of git://anongit.freedesktop.org/drm-intel into drm-fixes

Revert of a VBT parsing commit that should've been queued for drm-next,
not v4.2. The revert unbreaks Braswell among other things.

Also on Braswell removal of DP HBR2/TP3 and intermediate eDP frequency
support. The code was optimistically added based on incorrect
documentation; the platform does not support them. These are cc: stable.

Finally a gpu state fix from Chris, also cc: stable.
