Set the mux accordingly. The USB controller and EVM supports super-speed for USB0 on the Type-C port. However, the SERDES has a limitation that upto 2 protocols can be used at a time. The SERDES is wired for PCIe, eDP and USB super-speed. It has been chosen to use PCIe and eDP as default. So restrict USB0 to high-speed mode.
