drm_atomic_get_colorop_state() allocates a new colorop state by duplicating the current one and inserts it into the atomic commit as a single operation.
However, a later change will need to insert a colorop state into a commit without going through the full allocation and duplication path in drm_atomic_get_colorop_state(). Extract the state insertion logic into a new static drm_atomic_commit_set_colorop_state() helper, and convert drm_atomic_get_colorop_state() to use it.
