[PATCH 1/1] drm: bridge: Mark deprecated operations in drm_bridge_funcs

drm_bridge_funcs includes several duplicated operations as atomic
variants has been added over time.
New bridge drivers shall use the atomic variants - mark the deprecated
operations to try to avoid usage in new bridge drivers.
