fwnode matching was designed to match on nodes corresponding to a device. Some drivers, however, needed to match on endpoints, and have passed endpoint fwnodes to v4l2-async. This works when both the subdev and the notifier use the same fwnode types (endpoint or device), but makes drivers that use different types incompatible. Fix this by extending the fwnode match to handle fwnodes of different types. When the types (deduced from the presence of remote endpoints) are different, retrieve the device fwnode for the side that provides an endpoint fwnode, and compare it with the device fwnode provided by the other side. This allows interoperability between all drivers, regardless of which type of fwnode they use for matching.
