dt-bindings: power: supply: Drop deprecated ab8500-battery

Linus Walleij modified AB8500 to use the generic simple-battery
and samsung,battery bindings. This is an unused leftover that
can be removed.

-AB85000 PMIC contains a node, which contains shared
-information about the battery connected to the PMIC.
-The node has no compatible property.
-
-Properties of this node are:
-
-thermistor-on-batctrl:
-       A boolean value indicating thermistor interface to battery
-
-       Note:
-       'btemp' and 'batctrl' are the pins interfaced for battery temperature
-       measurement, 'btemp' signal is used when NTC(negative temperature
-       coefficient) resister is interfaced external to battery whereas
-       'batctrl' pin is used when NTC resister is internal to battery.
-
-       Example:
-       ab8500_battery: ab8500_battery {
-               thermistor-on-batctrl;
-       };
-       indicates: NTC resister is internal to battery, 'batctrl' is used
-               for thermal measurement.
-
-       The absence of property 'thermal-on-batctrl' indicates
-       NTC resister is external to battery and  'btemp' signal is used
-       for thermal measurement.
-
-battery-type:
-       This shall be the battery manufacturing technology type,
-       allowed types are:
-               "UNKNOWN" "NiMH" "LION" "LIPO" "LiFe" "NiCd" "LiMn"
-       Example:
-       ab8500_battery: ab8500_battery {
-               stericsson,battery-type = "LIPO";
-       }
