Some drivers might want to embed struct drm_colorop inside driver-specific objects, similar to planes or CRTCs. In such cases, freeing only the drm_colorop is incorrect.
Add a drm_colorop_funcs callback to allow drivers to provide a destroy hook that cleans up the full enclosing object. Make changes in helper functions to accept helper functions as argument. Pass NULL for now to retain current behavior.
