dt-bindings: power: supply: cpcap-battery: Convert to DT schema format 



Convert the binding to DT schema format. I also added the missing bits
used by the only in-tree user and implemented in the driver.

Motorola CPCAP PMIC battery driver binding



Required properties:

- compatible: Shall be "motorola,cpcap-battery"

- interrupts: Interrupt specifier for each name in interrupt-names

- interrupt-names: Should contain the following entries:

		   "lowbph", "lowbpl", "chrgcurr1", "battdetb"

- io-channels: IIO ADC channel specifier for each name in io-channel-names

- io-channel-names: Should contain the following entries:

		    "battdetb", "battp", "chg_isense", "batti"

- power-supplies: List of phandles for power-supplying devices, as

		  described in power_supply.txt. Typically a reference

		  to cpcap_charger.



Example:



cpcap_battery: battery {

	compatible = "motorola,cpcap-battery";

	interrupts-extended = <

		&cpcap 5 0 &cpcap 3 0

		&cpcap 20 0 &cpcap 54 0

	>;

	interrupt-names =

		"lowbph", "lowbpl",

		"chrgcurr1", "battdetb";

	io-channels = <&cpcap_adc 0 &cpcap_adc 1

		       &cpcap_adc 5 &cpcap_adc 6>;

	io-channel-names = "battdetb", "battp",

			   "chg_isense", "batti";

	power-supplies = <&cpcap_charger>;

};
