device property: Add helper to match multiple connections
In some cases multiple connections with the same connection id
needs to be resolved from a fwnode graph.
One such example is when separate hardware is used for performing muxing
and/or orientation switching of the SuperSpeed and SBU lines in a USB
Type-C connector. In this case the connector needs to belong to a graph
with multiple matching remote endpoints, and the Type-C controller needs
to be able to resolve them both.
Add a new API that allows this kind of lookup.
