X-Git-Tag: v6.16-rc1~28^2~68

dt-bindings: usb: usb-switch: Allow data-lanes property in port

The ref /schemas/graph.yaml#/properties/port forbids extra properties
which might be specified in subschemas, e.g. like in
usb/fcs,fsa4480.yaml.

Switch to port-base (and specify the endpoint with properties) to allow
such properties.
