On some boards, especially when vbus supply requires large current, and the charge pump on the PHY isn't enough, an external vbus power switch per port may be used. Add portN_vbus-supply property to usb-ehci bindings. As the number of ports depends on the ehci controller, and the port on which an external vbus supply depends on the platform, <portN> is used to make it generic.
