[RESEND 6/9] drm: Clean up colorop objects during mode_config cleanup

[Chaitanya Kumar Borah <chaitanya.kumar.borah@intel.com>]

Tear down all registered drm_colorop objects during
drm_mode_config_cleanup() by invoking their destroy callbacks.

This ensures proper cleanup of color pipeline objects during DRM device
removal.
