dt-bindings:iio:adc:adi,ad7949 yaml conversion

* Analog Devices AD7949/AD7682/AD7689

Required properties:

 - compatible: Should be one of

	* "adi,ad7949"

	* "adi,ad7682"

	* "adi,ad7689"

 - reg: spi chip select number for the device

 - vref-supply: The regulator supply for ADC reference voltage

Example:

adc@0 {

	compatible = "adi,ad7949";

	reg = <0>;

	vref-supply = <&vdd_supply>;
