kefka: Keep giving charge voltage/current when wake up dead battery
LGC and BYD battery will give charge voltage 0 and charge current 0
about 5 seconds when the battery wakes up. It will cause charger stops
and fail to wake up the battery. Force to give max charge voltage and
precharge current after the battery wakes up to prevent the issue.
BUG=b:64152371;b:64148243
BRANCH=firmware-strago-7287.B
TEST=Make system with LGC/BTD to over discharge state. Make sure that
we can wake up the system.
