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

Browse Source 
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>;
				};
			};
		};
	};
};
