[RESEND 1/9] drm/colorop: Add destroy helper for colorop objects

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

Add a helper that performs common cleanup and frees the
associated object. This can be used by drivers if they do not
require any driver-specific teardown.

v2:
- Add function documentation only before definition (Jani)
