The max17040 fuel gauge is part of a family of 8 chips that have very
similar mode of operations and registers.

This patch set adds:
- compatible strings for all supported devices and handles the minor
  differences between them;
- handling for devices reporting double capacity via maxim,double-soc;
- handling for setting rcomp, a compensation value for more accurate
  reading, affected by battery chemistry and operating temps;
- suppot for SOC alerts (capacity changes by +/- 1%), to prevent polling
  every second;
- improved max17040 driver with regmap and devm_

The datasheets of the supported devices are linked [0] [1] [2] [3].

Changes from v4:
- fix warning reported by kernel test robot <lkp@intel.com> for v4
  patch 4/7
- ensure all patches have Sign-off-by matching author (was violated
  for v4 patch 2/7)
