poppy: Fix charger_profile_override

Browse Source 
When battery is cutoff, it might at times require some current to be
applied to it so that it can wake up. Thus, in case where all battery
flags indicate error in charger_profile_override, set
requested_current and requested_voltage to precharge_current and
voltage max. This allows the battery to be woken up.

BUG=b:64370648,b:64460667
BRANCH=None
TEST=Verified that on connecting AC power after battery-cutoff, there
are no "try to wake battery" messages anymore.
