[Intel-gfx] [PATCH 00/12] drm/i915: Adding NV12 for skylake display

This patch series is adding NV12 support for Skylake display after
rebasing on latest drm-intel-nightly. Earlier I had two patch
series one for 0/180 and another for 90/270. Some of the patches
were already merged. This is combined series to support 0/90/180/270
and removing the ones that are already merged.

Feature is tested with igt/kms_nv12 testcase.
Feature is unit tested for linear/X/Y/Yf formats in 0, 90, 180, 270
orientations with combinations of 1, 2 or 3 planes enabled along with
scaling. Also negatively tested for enabling NV12 on unsupported

The last patch in this series depends on Tvrtko's GEM remapping
for NV12 format patch series.
