power: qpnp-smbcharger: add workaround to fix battery OV misfire

On some PMIC parts falling OV(over voltage) threshold for battery_ov
comparator is lower than the VFLT(float) voltage this prevents comparator
to reset causing a battery_ov misfire. Add a workaround to disable
BATT_OV_ECC (battery OV ends charge cycle) feature to prevent charging
termination.
