Motorola CPCAP PMIC ADC binding

Required properties:
- compatible: Should be "motorola,cpcap-adc" or "motorola,mapphone-cpcap-adc"
- interrupt-parent: The interrupt controller
- interrupts: The interrupt number for the ADC device
- interrupt-names: Should be "adcdone"
- #io-channel-cells: Number of cells in an IIO specifier

Example:

cpcap_adc: adc {
	compatible = "motorola,mapphone-cpcap-adc";
	interrupt-parent = <&cpcap>;
	interrupts = <8 IRQ_TYPE_NONE>;
	interrupt-names = "adcdone";
	#io-channel-cells = <1>;
};
