Document the "port" property, which is used with "usb-role-switch" to describe the bus connector. Definition is inspired from mediatek,mtu3.yaml.

usb-role-switch without port is valid or both must be present. In case of the latter, you need to add: usb-role-switch: [ port ] Also, you don't need quotes.
