dt-bindings:iio:adc:nxp,lpc3220-adc yaml conversion 



Renamed to remove the wild cards.  These go wrong far too often so
in general preferred to use the name of a specific part.  As this
binding only provides one compatible, I went with that.

* NXP LPC32xx SoC ADC controller



Required properties:

- compatible: must be "nxp,lpc3220-adc"

- reg: physical base address of the controller and length of memory mapped

  region.

- interrupts: The ADC interrupt



Optional:

 - vref-supply: The regulator supply ADC reference voltage, optional

   for legacy reason, but highly encouraging to us in new device tree



Example:



	adc@40048000 {

		compatible = "nxp,lpc3220-adc";

		reg = <0x40048000 0x1000>;

		interrupt-parent = <&mic>;

		interrupts = <39 0>;

		vref-supply = <&vcc>;

	};
