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>;
- };
