Add support for the Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC. It was suggested to combine this functionality with the current ds2782 driver. Unfortunately, I'm unable to commit the time to refactoring this driver to that extent and I don't have a platform with the ds2782 part to validate that there are no regression issues by adding this functionality.
