drm/bridge: Add a drm_bridge_state object
One of the last remaining objects to not have its atomic state. This is being motivated by our attempt to support runtime bus-format negotiation between elements of the bridge chain. This patch just paves the road for such a feature by adding a new drm_bridge_state object inheriting from drm_private_obj so we can re-use some of the existing state initialization/tracking logic.
