Most of the chips only return one type of SOC, and the docs refer to this
as just "State-of-Charge". The bq27000 has "Relative" and " Compensated"
but we only return one (Relative). So I figured this would be the more
correct way to describe the general SOC reading function even when the
chips may expose other types.
