power/supply: unify DT documentation
Currently the power supply device tree documentation is spread in .../bindings/power_supply and .../bindings/power. This unifies the files for chargers and battery fuel gauges in .../bindings/power/supply and the ones for system reset/shutdown in .../bindings/power/reset (same structure as used for the drivers itself).

+gpio-charger
+
+Required properties :
+ - compatible : "gpio-charger"
+ - gpios : GPIO indicating the charger presence.
+ See GPIO binding in bindings/gpio/gpio.txt .
+ - charger-type : power supply type, one of
+ unknown
+ battery
+ ups
+ mains
+ usb-sdp (USB standard downstream port)
+ usb-dcp (USB dedicated charging port)
+ usb-cdp (USB charging downstream port)
+ usb-aca (USB accessory charger adapter)
+
+Example:
+
+ usb_charger: charger {
+ compatible = "gpio-charger";
+ charger-type = "usb-sdp";
+ gpios = <&gpf0 2 0 0 0>;
+ }
+
+ battery {
+ power-supplies = <&usb_charger>;
+ };
