usb: typec: mux: add Qualcomm WCD939X USB SubSystem Altmode Mux driver
Qualcomm WCD9390/WCD9395 is a standalone Hi-Fi audio codec IC with a
functionally separate USB SubSystem for Altmode/Analog Audio Switch
accessible over an I2C interface.
It provides switching USB-C USB2.0 lines between USB and Audio Headphones
speaker lines, and the USB-C SBU lines between DisplayPort AUX and Audio
Headphones Microphone/Ground.
The Audio Headphone and Microphone data path between the Codec and the
USB-C Mux subsystems are external to the IC, thus requiring DT
port-endpoint graph description to handle USB-C altmode & orientation
switching for Audio Accessory Mode.
