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.
