[PATCH v2 14/14] power: max77693_charger: Add supplied_to info to power_supply_config

[Hans de Goede <hdegoede@redhat.com>]

On the exynos4412-trats2 the max77693 is used together with a
max17047 fuel-gauge. Add supplied_to info containing "main-battery",
so that the get_status code in the max17042_battery driver can use
power_supply_am_i_supplied and can properly let userspace know
if the battery is being charged or not.
