Add a Devicetree binding for the USB device controller integrated into the Axiado AX3000 and AX3005 SoCs. The controller is based on the Corigine USB 3.1 device IP core and supports High-Speed and SuperSpeed operation. The standard maximum-speed property can be used to limit the controller to High-Speed operation.
