[v3,2/7] drm/bridge-connector: switch to using drmm allocations

Commit Message

Turn drm_bridge_connector to using drmm_kzalloc() and
drmm_connector_init() and drop the custom destroy function. The
drm_connector_unregister() and fwnode_handle_put() are already handled
by the drm_connector_cleanup() and so are safe to be dropped.
