power: qpnp-smbcharger: Add support to adjust the battery soc configuration 



If the charger is present and charging is terminated or the charger
is in taper mode charging and battery capacity is already 100%,
then notify the fuel gauge through POWER_SUPPLY_PROP_CHARGE_FULL
property so that it can adjust the soc configuration.
