With cpcap-charger now using 4.2V instead of 4.35V, we never reach
POWER_SUPPLY_CAPACITY_LEVEL_FULL unless we handle the lowered charge
voltage.
Let's do this by implementing POWER_SUPPLY_PROP_CONSTANT_CHARGE_VOLTAGE,
and assume anything at that level or higher is a full battery.
Let's also make it configurable for users who may still want to
reconfigure it, and notify the charger if supported by the charger.
