dt-bindings: power: supply: cpcap-charger: 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 charger binding



Required properties:

- compatible: Shall be "motorola,mapphone-cpcap-charger"

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

- interrupt-names: Should contain the following entries:

		   "chrg_det", "rvrs_chrg", "chrg_se1b", "se0conn",

		   "rvrs_mode", "chrgcurr2", "chrgcurr1", "vbusvld",

		   "battdetb"

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

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

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



Optional properties:

- mode-gpios: Optionally CPCAP charger can have a companion wireless

	      charge controller that is controlled with two GPIOs

	      that are active low.



Example:



cpcap_charger: charger {

	compatible = "motorola,mapphone-cpcap-charger";

	interrupts-extended = <

		&cpcap 13 0 &cpcap 12 0 &cpcap 29 0 &cpcap 28 0

		&cpcap 22 0 &cpcap 21 0 &cpcap 20 0 &cpcap 19 0

		&cpcap 54 0

	>;

	interrupt-names =

		"chrg_det", "rvrs_chrg", "chrg_se1b", "se0conn",

		"rvrs_mode", "chrgcurr2", "chrgcurr1", "vbusvld",

		"battdetb";

	mode-gpios = <&gpio3 29 GPIO_ACTIVE_LOW

		      &gpio3 23 GPIO_ACTIVE_LOW>;

	io-channels = <&cpcap_adc 0 &cpcap_adc 1

		       &cpcap_adc 2 &cpcap_adc 5

		       &cpcap_adc 6>;

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

			   "vbus", "chg_isense",

			   "batti";
