chgstv2: optimization battery protection for low voltage
Deep_charge_battery needs to precharge first, and then enter the idle or
charge state. Because before entering deep_charge_battery, the curr.state
state may be the idle state, which may cause no precharge process.
Therefore, add a flag to curr.batt.flags for record whether the precharge
process has been performed.
BRANCH=trogdor
BUG=b:263921114
TEST=After the battery is discharged below voltage_min, the charging
process enters deep_charge_battery and precharges first, and when the
battery voltage is greater than voltage_min, it enters the charge
state and charges normally.
TEST=run-battery_get_params_smart
