BD9995X/reef/snappy/pyro: Boot from the shipmode battery
Charger BGATE is off on POR hence the voltage to the battery pack is
not applied immediately from the VBUS. To overcome this issue, BGATE
is turned on (CHG_EN) at charger initialization. If the voltage across
VBATT is high but I2C is still failing, battery is booting from ship
mode hence overwrite the battery as not present till I2C on battery
is success and INIT bit is set.
BUG=chrome-os-partner:59308
BRANCH=none
TEST=Reef can boot to OS from shipmode battery.
