power_supply: Add constant charge_current and charge_voltage properties
Constant Charge Current(CC) is charging parameter which limit the maximum current which can be pumped into the battery during charge cycle. Constant Charge Voltage(CV) is also charging parameter which limit the maximum voltage that battery can reach during charge cycle. It is very common practice that at low or high temperatures we do not charge the batteries upto it's fullest charge voltage to avoid battery and user safety issues. These sysfs properties will be useful for debug and to implement certain user space policies like "Charging limited due to OverTemp".
