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";
};
