[PATCH 05/10] power: supply: charger-manager: Collect all power_supply_changed() calls

[Jonathan Bakker <xc-racer2@live.ca>]

From: Jonghwa Lee <jonghwa3.lee@samsung.com>

Current charger-manager calls power_supply_changed() whenever charging
status is changed. Remove the separated power_supply_changed() calls
and let it be called at end of try_charger_enable() function which
is called to set charging/discharging.
