Add LTC2941/LTC2943 Battery Gauge Driver
Both the LTC2941 and LTC2943 measure battery capacity. The LTC2943 is compatible with the LTC2941, it adds voltage and temperature monitoring, and uses a slightly different conversion formula for the charge counter. To avoid confusion with e.g. the LTC2945, the driver is called LTC2941 instead of LTC294X. v2: Fix units of measurement: uV, uA and centidegrees. v3: Correctly set configuration register. Allow negative values for the sense resistor. v4: Run checkpatch.pl and fix all errors and warnings. v5: Prefix "lltc," to devicetree properties.
