regulator: dt-bindings: Convert Fairchild FAN53555 to DT schema 



Convert the Fairchild FAN53555 and compatible variants binding to DT
schema format.

Add the undocumented 'vsel-gpios' property used to control the VSEL pin.

The example was missing 'reg', so add it.

Binding for Fairchild FAN53555 regulators



Required properties:

  - compatible: one of "fcs,fan53555", "fcs,fan53526", "silergy,syr827",

		"silergy,syr828" or "tcs,tcs4525".

  - reg: I2C address



Optional properties:

  - fcs,suspend-voltage-selector: declare which of the two available

		voltage selector registers should be used for the suspend

		voltage. The other one is used for the runtime voltage setting

		Possible values are either <0> or <1>

  - vin-supply: regulator supplying the vin pin



Example:



	regulator@40 {

		compatible = "fcs,fan53555";

		regulator-name = "fan53555";

		regulator-min-microvolt = <1000000>;

		regulator-max-microvolt = <1800000>;

		vin-supply = <&parent_reg>;

		fcs,suspend-voltage-selector = <1>;

	};
