Fairchild FUSB302 Type-C Port controllers

Required properties :
- compatible             : "fcs,fusb302"
- reg                    : I2C slave address
- interrupts             : Interrupt specifier

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:

	compatible = "fcs,fusb302";
	reg = <0x54>;
	interrupt-parent = <&nmi_intc>;
	interrupts = <0 IRQ_TYPE_LEVEL_LOW>;

	usb_con: connector {

			     PDO_VAR(3000, 12000, 3000)
