More generally this is used together with the already documented
usb-role-switch property to connect the dwc3 to the Type-C connector.
Which makes me feel that we don't actually need ports/port, but could do
with just port? Perhaps I'm missing some usecase?
I'm somewhat confused to why this isn't already documented...
Ack. Will document this as a port.
