Many users of drm_gem_object embed a struct reservation_object into their subclassed struct, so let's add one to struct drm_gem_object. This will allow removing the reservation object from the subclasses and removing the ->gem_prime_res_obj callback. With the addition, add a drm_gem_reservation_object_wait() helper function for drivers to use in wait ioctls.
