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
