battery : Define CONFIG_BATTERY_DEAD_UNTIL_VALUE
It takes 850ms~950ms to get valid RSOC after battery wake-up.
Sometimes battery FG returns garbage data(1%)
as RSOC and 0 value of desired current / voltage.
Add CONFIG_BATTERY_DEAD_UNTIL_VALUE to continue charging.
BUG=b:138413964
BRANCH=None
TEST=build & flash, check battery charging with dead battery
