media: v4l2-fwnode: ignore endpoints that have no remote port parent
Documentation/devicetree/bindings/media/video-interfaces.txt states that
the 'remote-endpoint' property is optional.
So v4l2_async_notifier_fwnode_parse_endpoint() should not return error
if the endpoint has no remote port parent. Just ignore the endpoint,
skip adding an asd to the notifier and return 0.
__v4l2_async_notifier_parse_fwnode_endpoints() will then continue
parsing the remaining port endpoints of the device.
