drivers/intel/usb4: Add mainboard function to get EC port

This patch adds mainboard override function which allows for
custom port mapping between CPU physical port and EC port to
accommodate the non-sequential mapping. Mainboard code must
implement this function if the CPU physical port to EC port
mapping is not sequential.

BUG=b:399032094
TEST=build and verify TCSS port and EC port mapping
