regulators: Close devices when system powering off

Modify the Manager class to close all regulator devices when monitoring
is disabled.  Monitoring is normally disabled because the system is
being powered off.

Also add a closeDevices() method to the System class that closes all
devices in the system.

Tested:
  * Tested when monitoring was disabled.  Verified debug journal message
    stating devices were closed.
  * Tested multiple consecutive power on/off cycles to ensure device
    access remained functional.
  * Performed regression test on existing function.
  * Created and executed automated tests for System::closeDevices()
