charger-manager: Add support sysfs entry for charger
This patch add support sysfs entry for each charger(regulator).
Charger-manager use one or more chargers for charging battery but some
charger isn't necessary on specific scenario. So, if some charger isn't
needed, can disable specific charger through 'externally_control' entry
while system is on state and confirm the information(name, state) of
charger.
The list of added sysfs entry
- /sys/class/power_supply/battery/chargers/charger.[index]/name
show name of charger(regulator)
- /sys/class/power_supply/battery/chargers/charger.[index]/state
show either enabled or disabled state of charger
- /sys/class/power_supply/battery/chargers/charger.[index]/externally_control
If 'externally_control' of specific charger is 1, Charger-manager cannot
enable regulator for charging when charger cable is attached and charger
must be maintained with disabled state. If 'externally_control' is zero,
Charger-manager usually can control to enable/disable regulator.
