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.
