1. drivers: thermal: step_wise: add support for hysteresis …

   Step wise governor increases the mitigation level when the temperature
   goes above a threshold and will decrease the mitigation when the
   temperature falls below the threshold. If it were a case, where the
   temperature hovers around a threshold, the mitigation will be applied
   and removed at every iteration. This reaction to the temperature is
   inefficient for performance.
   
   The use of hysteresis temperature could avoid this ping-pong of
   mitigation by relaxing the mitigation to happen only when the
   temperature goes below this lower hysteresis value.
