Some battery driver will use the open circuit voltage (OCV) value to look
up the corresponding battery capacity percent in one certain degree Celsius.
Thus this patch provides some battery properties to present the OCV table
temperatures and OCV capacity table values.

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.

Documentation of static battery characteristics that can be defined
for batteries that do not embed this data, which are required by
fuel-gauge and charger chips for proper handling of the battery.
The following properties are defined:
voltage-min-design-microvolt
charge-full-design-microamp-hours
energy-full-design-microwatt-hours
precharge-current-microamp
charge-term-current-microamp
constant-charge-current-max-microamp
constant-charge-voltage-max-microamp
Property names are derived from corresponding elements in
enum power_supply_property from include/linux/power_supply.h
