Many fuel gauge ICs offer a battery cutoff/shipping mode functionality that
cutoff charge from the battery. This is often useful for preserving battery
charge on devices while in storage.
Add battery cutoff support to the fuel gauge API with a generic default SBS
driver showing an example of support in tests.

Drop compatible from fuel-gauge.yaml, it's not needed since this binding
is not meant to be used directly, and is also incorrect as it includes
the "yaml" suffix.

Add a sample sbs gauge driver with feature parity and basic tests
comparison to its sensor counter-part. Includes a simple stub test that is
extended upon.
