regulators: Add clearErrorHistory to Device class
Add a clearErrorHistory() method to the Device class. The method should
clear all data on previously logged errors. If the error occurs again
in the future, it will be logged again.
This method is normally called when the system is being powered on. For
code that runs repeatedly, errors are only logged once per boot.
When the system is powered off, hardware may be replaced that fixes the
problem. Thus, errors are cleared during power on.
