oak: allow charging of dead battery requesting nil

Browse Source 
On oak 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 oak battery is used and a charger is
connected, we attempt to charge it.

BUG=chrome-os-partner:51454
BRANCH=none
TEST=test on an oak 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.
