drm/colorop: Introduce DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE
With the introduction of the pre-blending color pipeline we
can no longer have color operations that don't have a clear
position in the color pipeline. We deprecate all existing
plane properties. For upstream drivers those are:
- COLOR_ENCODING
- COLOR_RANGE
Drivers are expected to ignore these properties when
programming the HW. DRM clients that register with
DRM_CLIENT_CAP_PLANE_COLOR_PIPELINE will not be allowed to
set the COLOR_ENCODING and COLOR_RANGE properties.
Setting of the COLOR_PIPELINE plane property or drm_colorop
properties is only allowed for userspace that sets this
client cap.
