Update the SBS Gauge driver that implements the fuel_gauge API to implement
a set_property function allowing the writing of an SBS word to the
manufacturer access register per the SBS spec.
Includes an update to the SBS Gauge emulator and SBS fuel gauge tests to
weakly verify the code runs.

The SBS fuel gauge driver did not return a count of the number of
properties that failed.
Fix this and add a test that verifies the sbs_gauge returns the number of
failing properties as well as a test that verifies a negative return code
if all properties failed.

comparison to its sensor counter-part. Includes a simple stub test that is
extended upon.
