In order to pass functions to kunit_add_action(), they need to be of the kunit_action_t type. While casting the function pointer can work, it will break control-flow integrity.
vc4_mock already defines such a wrapper for drm_dev_unregister(), but it involves less boilerplate to use the new macro, so replace the manual implementation.

This patch should be a no-op, just moving to use a standard macro to implement these wrappers rather than hand-coding them.
Let me know if you'd prefer to take these in separately via the drm trees, or if you're okay with having this whole series go via kselftest/kunit.
Cheers, -- David
