drm/i915/skl+: Check for supported plane configuration in Interlace mode
In Gen9 platform Interlaced fetch mode doesn't support following plane
configuration:
- Y/Yf tiling
- 90/270 rotation
- YUV420 hybrid planar source pixel formats.
This patch adds check to fail the flip if any of the above configuration
is requested.
Changes since V1:
- handle checks in intel_plane_atomic_check_with_state (ville)
- takeout plane scaler checks combile with pipe scaler in next patch
Changes since V2:
- No need to check for NV12 as it need scaling, so it will be rejected
by scaling check (ville)
