rebasing to v3.15 would need too many backports to core drm so that plan
was scrapped, use the last i915 tag for v3.15 that doesn't pull core drm
work

** Summary changed:

- Rebase Broadwell graphics support to v3.15
+ Rebase Broadwell graphics support to drm-intel-next-2014-03-07

** Description changed:

  i915_bdw driver module in the trusty kernel is currently based on
  v3.14+backports, but it has turned out to be insufficient on real
  systems causing system freezes and/or GPU hangs with certain workloads.
  Some issues have been worked around but they trigger other bugs, and
  backporting bisected fixes dind't fix them on this branch.
  
- Rebasing the driver to v3.15 brings a lot of fixes and a better platform
- for future work.
+ Rebasing the driver to the latest tag from i915 upstream that doesn't
+ include changes to core drm, plus additional fixes, should provide a
+ better driver for the initial broadwell enablement.
