platform/x86: x86-android-tablets: Add battery swnode support
power_supply_get_battery_info() which is used by charger and fuel-gauge
drivers on x86-android-tablets, expects the battery properties to be
described in a stand-alone battery fwnode which is then referenced
from both the charger and fuel-gauge device's fwnodes.
Add support for registering + unregistering a swnode for this.
