On samus battery, when the battery is dead it reports 0 for desired
voltage, current, and state of charge. In this case we should allow
charging.
Added a CONFIG option for this that should be removed as soon as
the battery side is fixed.
With this CL, when a dead samus battery is used and a charger is
connected, we attempt to charge it.
BUG=chrome-os-partner:29465
BRANCH=none
TEST=test on a samus with a dead battery. w/o this CL, the battery
never charges because the charging not allowed flag is set. With this
CL, the battery charges.
