MAX17043 sensor integration (#18788)
* Restart MAX17043 from the scratch

* revert change

* Changed battery capacity in charge (capacity is the Ah value of the battery, this degrades over time when battery ages)

* merge

* Changing xsns_109 to 110

* fix nr

* removed old xsns109

* Update I2CDEVICES.md

* clean-up usage of Interface
