From: Harry Wentland <harry.wentland@xxxxxxx>
Drivers will need to know whether an atomic check/commit
originated from a client with DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE
so they can ignore deprecated properties, like COLOR_ENCODING
and COLOR_RANGE.
Pass the plane_color_pipeline bit to drm_atomic_state.
