power_supply: get_by_name and set_charged functionality
This adds a function that indicates that a battery is fully charged. It also includes functions to get a power_supply device from the class of registered devices by name reference. These can be used to find a specific battery to call power_supply_set_battery_charged() on. Some battery drivers might need this information to calibrate themselves.
