The Qualcomm X1E80100 QCP has FSUSB42 USB switches on each of the USB-C
ports that handle orientation switching for the SBU lines. This is needed
to enable DisplayPort support for external displays.

Add the onnn,fsusb42 compatible to the existing gpio-sbu-mux binding and
then describe all the necessary components in the x1e80100-qcp device tree
to make external DP work correctly.
