Gregory CLEMENT caeffabc36 dt-bindings: iio: adc: lpc32xx-adc: Document vref-supply
As most of the other ADC the lpc32xx one use a vref-supply property:
document it.

* 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>;
};
