[Vivid SRU][PULL] Updates for i915_bpo, i915, hda_intel

[Timo Aaltonen]

	Hi

These are all combined in the same pull request, because they've been
tested together too, and some depend on the other. Fixes these bugs:

i915_bpo + core-drm updates:
http://bugs.launchpad.net/bugs/1449469

HDMI/DP audio for SKL/CHV:
http://bugs.launchpad.net/bugs/1449464

BDW rotation:

git://kernel.ubuntu.com/tjaalton/ubuntu-vivid.git i915-bpo


- "fast-forward" i915_bpo to 4.1-rc1
8d656f045d65861 i915_bpo: Update to 4.1rc1

- cherry-pick fixes and support for DRM_DEBUG_ATOMIC which makes
  normal drm.debug output useful (less noise)
- atomic is only used by i915_bpo, so no reason not to keep it
  closer to 4.1

A kernel built from this branch has been tested on intel gen4/6/7.5(hsw)/8/9 & radeon
without any noticeable regressions.
