regulators: Clear cached hardware data during boot
Clear cached data about hardware devices when the system is powering on
(booting).
While the system was powered off, hardware devices containing voltage
regulators could have been added, removed, or replaced. Cached hardware
data might now be invalid.
Tested:
* Ran automated test cases
* Verified that cached data is cleared without errors during boot
* When config file was found and loaded
* When no config file was found
