USB0 supports super-speed mode on the EVM. Enable that. On the EVM, USB0 uses SERDES3 for super-speed lane.
Since USB0 is a type-C port, it needs to support lane swapping for cable flip support. This is provided using SERDES lane swap feature. Provide the Type-C cable orientation GPIO to the SERDES Wrapper driver.
