Title:
  Fix S3 on some Valleyview/Baytrail systems, switch to i915_bdw

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Trusty:
  Fix Committed

Bug description:
  We've identified a commit in 3.16 to fix S3 on certain Baytrail
  systems, but it alone is not enough to fix the bug when backported  to
  3.13. Further investigation shows that it would likely need
  backporting chunks of i915 from 3.14 which is not feasible. The better
  option is to switch BYT to use i915_bdw, which has been tested to be
  stable.
