UCSI already conveys the information about a port's connection status, whether it is operating in UFP or DFP mode, and whether the partner supports USB data or not. This information can be used to notify a dual-role controller to start up its host or peripheral mode accordingly. Add optional support for this by querying each port's fwnode to look for an associated USB role switch device. If present, call usb_role_switch_set() with the determined data role upon Connect Change or Connector Partner Change updates.
