arm64: dts: rockchip: Enable USB 2.0 ports on Radxa E20C

Browse source

The Radxa E20C has one USB2.0 Type-A HOST port and one USB2.0 Type-C port.

The Type-C port is conneced to a FE1.1s_QFN USB hub on the board, with its
ports being connected to the XHCI usb controller and an usb-uart bridge.

This also means, the XHCI controller can only be used in device-mode.

Add support for using the USB 2.0 ports on Radxa E20C.
