Should add port@0 for usb_1_hsphy because it is required

Not by the hardware its not. The combophy is exclusively responsible for processing the orientation switch.

The only required port in usb-c-connector is port@0 i.e. you have to have one thing the usb-c-connector can connect to for data-role switching.

Now.. I'd take the input that <&qmpphy_typec_mux_in> is not documented but relies on

    usb: typec: tcpm: try to get role switch from tcpc fwnode

because that is the case.

I will add something to documentation to capture the case where we use a usb-c-connector to trigger an type-c mux orientation switch.
