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.
