dt-bindings: power: supply: ab8500: Convert to DT schema format 



Convert the binding to DT schema format.

Note: The battery node does not have a compatible value and needs
to be described from the binding file for the PMIC. That has not
yet been converted, so I kept the information in plaintext for now.

AB8500 is a mixed signal multimedia and power management

device comprising: power and energy-management-module,

wall-charger, usb-charger, audio codec, general purpose adc,

tvout, clock management and sim card interface.



Fuelgauge support is part of energy-management-modules, other

components of this module are:

main-charger, usb-combo-charger and battery-temperature-monitoring.



The properties below describes the node for fuelgauge driver.



Required Properties:

- compatible = This shall be: "stericsson,ab8500-fg"
