Subject: [PATCH 0/2] power: supply: add support for MAX1720x standalone fuel

Changes to max1721x_battery.c:
  - reading manufacturer, model name and serial number is only possible
    when SBS functions of the IC are enabled.(nNVCfg0.enSBS) Factory
    default is off. Manufacturer is "Maxim Integrated" and the model name
    can be derived by register MAX172XX_DEV_NAME. Serial number is not
    available anymore.
  - According to the datasheet MAX172XX_BAT_PRESENT is at BIT(3) not
    BIT(4). Furthermore the naming is misleading, when BIT(3) is set the
    battery is not present.
  - Removed DeviceName, ManufacturerName and SerialNumber from struct
    max17211_device_info
