This property is meant to be used in device nodes which represent
power_supply devices that wish to provide a list of supplies to
which they provide power. A common case is a AC Charger with
the batteries it powers.

v2:
- Changed property to "power-supply" which should be contained in the
battery rather than the charger. Also updated example to match.
