configurations: minerva_cmm_scm: add hysteresis

The hysteresis value is set to 2% of the trigger threshold
to ensure more precise triggering of assert and deassert for
sensors like a 12V sensor. For example, with normal readings
and thresholds at ±10% (10.8V to 13.2V), the default value of
2.55 is too large for this range.
