dt-bindings: power: Introduce one property to present the battery internal resistance
The internal resistance of a battery is not a constant in its life cycle, this varies over the age of the battery or temperature and so on. But we just want use one constant battery internal resistance to estimate the battery capacity. Thus this patch introduces one property to present the battery factory internal resistance for battery information.
