power: supply: bq27xxx_battery: Add the BQ28z610 Battery monitor 

Add the Texas Instruments BQ28z610 battery monitor.
The register address map is laid out the same as compared to other
devices within the file.

The battery status register bits are similar to the bq27z561 but they
are different compared to other fuel gauge devices within this file.
