casta:Do not override charge on dead battery
charger_profile_override() change charging voltage & current
as battery temperature. The flag for bad temperature is set
when battery is not responsive then the current is set to 0.
Charge doesnot charge dead battery and the battery can't wake.
Then the system can't power on with dead battery.
BUG=b:131126731
BRANCH=octopus
TEST=flash EC and check if dead battery is charged.
