regulator: max8998: Add charger regulator
The max8998 has a current regulator for charging control.  The
charger driver in drivers/power/supply/max8998_charger.c has a
comment in it stating that 'charger control is done by a current
regulator "CHARGER"', but this regulator was never added until
now.

The current values have been extracted from a downstream driver
for the SGH-T959V.
