If the battery is not yet ready to provide the power or battery is
not present and the charging current is set to 64mA then the charger
voltage regulation is transient. ROHM recommended 512mA of minimum
charging current for this issue, hence changed the minimum charging
current from 64mA to 512mA.
BUG=chrome-os-partner:54821
BRANCH=none
TEST=Manually tested on Amenia.
a. Until the battery is initialized from cut-off mode, charging
voltage doesn't drop below battery voltage max.
b. With 15W charger (5V, 3A) without the battery, charger voltage
is regulated to battery voltage max.
