power: supply: Add helpers to get and put arrays of power supply handles

Browse source

Add power_supply_get_system_batteries() to allow drivers to obtain
a list of registered battery type power supply references in the
system. Also add power_supply_put_system_batteries() to perform
cleanup after the former function is called.
