power: smb1351-charger: Add support to work with FG 



Add following features to support working with Fuel gauge(FG).
  1) Force ESR pulse when charging and SoC is changed;
  2) Use FG for JEITA detection;
  3) Check FG status if charging termination reported and keep battery
      status consistent between FG and charger;
  4) Add SoC based recharging
