dt-bindings: usb: fusb302: Use usb-connector bindings for configuration

- reg                    : I2C slave address

- interrupts             : Interrupt specifier

Optional properties :

- fcs,operating-sink-microwatt :

			   Minimum amount of power accepted from a sink

Required sub-node:

- connector : The "usb-c-connector" attached to the FUSB302 IC. The bindings

  of the connector node are specified in:

	Documentation/devicetree/bindings/connector/usb-connector.txt

Deprecated properties :

- fcs,max-sink-microvolt : Maximum sink voltage accepted by port controller

- fcs,max-sink-microamp : Maximum sink current accepted by port controller

- fcs,max-sink-microwatt : Maximum sink power accepted by port controller

- fcs,operating-sink-microwatt : Minimum amount of power accepted from a sink

  when negotiating

Example:

fusb302: typec-portc@54 {

	reg = <0x54>;

	interrupt-parent = <&nmi_intc>;

	interrupts = <0 IRQ_TYPE_LEVEL_LOW>;

	fcs,max-sink-microvolt = <12000000>;

	fcs,max-sink-microamp = <3000000>;

	fcs,max-sink-microwatt = <36000000>;

	usb_con: connector {

		compatible = "usb-c-connector";

		label = "USB-C";

		power-role = "dual";

		try-power-role = "sink";

		source-pdos = <PDO_FIXED(5000, 3000, PDO_FIXED_USB_COMM)>;

		sink-pdos = <PDO_FIXED(5000, 3000, PDO_FIXED_USB_COMM)

			     PDO_VAR(3000, 12000, 3000)

			     PDO_PPS_APDO(3000, 11000, 3000)>;

		op-sink-microwatt = <10000000>;
