fd2a052ccd dt-bindings: usb: add common Type-C USB Switch schema 
Several bindings implement parts of Type-C USB orientation and mode
switching, and retiming.  Keep definition of such properties in one
place, new usb-switch schema, to avoid duplicate defines.

de12c53843 dt-bindings: usb: Document WCD939x USB SubSystem Altmode/Analog Audio Switch 
Document the Qualcomm WCD9390/WCD9395 USB SubSystem Altmode/Analog Audio Switch
which is a separate USB SubSystem for Altmode/Analog Audio Switch accessible
over an I2C interface.

Since Audio Headphone and Microphone data path between the Codec and the USB-C Mux
subsystems are external to the IC, it requires a second port to handle USB-C altmode
& orientation switching for Audio Accessory Mode to the Codec SubSystem.
