phy: usbphyc: update xlate with DT binding

Parameter added for port 1, for example:

&usbh_ehci {
	phys = <&usbphyc_port0>;
	phy-names = "usb";
	vbus-supply = <&vbus_sw>;
	status = "okay";
};

&usbotg_hs {
	pinctrl-names = "default";
	pinctrl-0 = <&usbotg_hs_pins_a>;
	phys = <&usbphyc_port1 0>;
	phy-names = "usb2-phy";
	status = "okay";
};
