[PATCH 09/13] drm/i915/display: Hook up intel_colorop_destroy

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

i915 embeds struct drm_colorop inside struct intel_colorop, so the
default drm_colorop_destroy() helper cannot be used. Add an
intel_colorop_destroy() helper that performs common DRM cleanup and
frees intel_colorop object.

This ensures correct teardown of plane color pipeline objects.
