usb: typec: mux: Add On Semi fsa4480 driver
The ON Semiconductor FSA4480 is a USB Type-C port multimedia switch with
support for analog audio headsets. It allows sharing a common USB Type-C
port to pass USB2.0 signal, analog audio, sideband use wires and analog
microphone signal.
Due to lacking upstream audio support for testing, the audio muxing is
left untouched, but implementation of muxing the SBU lines is provided
as a pair of Type-C mux and switch devices. This provides the necessary
support for enabling the DisplayPort altmode on devices with this
circuit.
