This patch adds basic core dwc3, usb phy and rt1711h nodes for usb support on Hikey960. This does not enable the mux/hub functionality on the board, so the USB-A host ports will not function, but does allow the USB-C port to function in gadget mode (unfortunately not in host, as the hub/mux functionality is needed to enable vbus output to power devices in host mode). This is based on an old patch originally by Yu Chen.
