Try to get usb role switch from tcpc fwnode if failed to
get role switch from port dev, this is for case the port
for role switch endpoint is located in connector node,
as per connector binding doc, port@0 for HS is required.

ptn5110: tcpc@50 {
	compatible = "nxp,ptn5110";
	...
	status = "okay";

	connector {
		compatible = "usb-c-connector";
		label = "USB-C";
		...

		ports {
			#address-cells = <1>;
			#size-cells = <0>;

			port@0 {
				reg = <0>;

				typec_conn: endpoint {
					remote-endpoint = <&usb2_controller>;
				};
			};
		};
	};
};

This looks like exactly the same as the RFC from Bryan that I just
commented. I have not objections if this looks okay to you Brian. I
think we should still wait for comments also from Guenter.

thanks,

It does look exactly the same. I don't mind letting Li have the commit.
