chgstv2: optimization battery protection for low voltagefirmware-dedede-13606.516.B-master
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.
