In the future we will want to support the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR and then we will not have direct access to the connector. The atomic version '.atomic_enable' allows accessing the current connector from the state. This patch switches the bridge to the atomic version to prepare access to the connector in later patches.
