Ah, for some reason I assumed that the orientation switch will take care of that, but of course it does not. So we'll keep the existing connections, and just add a new one for the alt mode device. Sorry for this. Thanks,

PI3USB30532 is used for muxing the port to DisplayPort on CHT platforms, so changing the connection ID so that the mux will get assigned to the alternate mode device and not the port device. Connection ID "typec-mux" is now reserved for Accessory Modes.
