[PATCH v2 1/1] riscv: dts: spacemit: enable USB3 on OrangePi R2S

[Chukun Pan]

Enable the DWC3 USB3.0 controller and its associated PHY on the
OrangePi R2S. The USB regulator provides VBUS for USB2 and USB3
ports, but the USB2 ports are handled by a separate controller.

v2: Remove vin-supply for the vcc5v0_usb regulator.
