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.
