[PATCHv2 02/38] dt-bindings: power: supply: cpcap-battery: Convert to DT schema format

[Sebastian Reichel <sebastian.reichel@collabora.com>]

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>;
