bd8c3ce6d7 dt-bindings: usb: switch: split out ports definition 
The ports definition currently defined in the usb-switch.yaml
fits standards devices which are either recipient of altmode
muxing and orientation switching events or an element of the
USB Super Speed data lanes.

This doesn't necessarely fit combo PHYs like the Qualcomm
USB3/DP Combo which has a different ports representation.

Move the ports definition to a separate usb-switch-ports.yaml
and reference it next to the usb-switch.yaml, except for
the Qualcomm USB3/DP Combo PHY bindings.

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.
