Neil Armstrong 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.
