From: Stanislav Lisovskiy <stanislav.lisovs...@intel.com>
PLANE_CTL_FORMAT_AYUV is already supported, according to hardware specification.
v2: Edited commit message, removed redundant whitespaces.
v3: Fixed fallthrough logic for the format switch cases.
v4: Yet again fixed fallthrough logic, to reuse code from other case
labels.
v5: Started to use XYUV instead of AYUV, as we don't use alpha.
v6: Removed unneeded initializer for new XYUV format.
v7: Added scaling support for DRM_FORMAT_XYUV
v8: Edited commit message to be more clear about skl+, renamed
PLANE_CTL_FORMAT_AYUV to PLANE_CTL_FORMAT_XYUV as this format
doesn't support per-pixel alpha. Fixed minor code issues.
v9: Moved DRM format check to proper place in intel_framebuffer_init.
v10: Added missing XYUV format to sprite planes for skl+.
v11: Changed DRM_FORMAT_XYUV to be DRM_FORMAT_XYUV8888.
v12: Fixed rebase conflicts
V13: Rebased.
Added format to ICL format lists.
v12:

This has been updated to support GEN11 along with rebasing it to
the latest drm-tip. A patch to igt has also been posted that gives
igt the ability to test this format.
