The board uses lane 1 of SERDES for USB. 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 up to 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.
