w1: add Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC support
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.
