It only adds the basic functions from ResetSystemRuntimeDxe. Lacking of this interface may cause link error, if some drivers use this new API and link to this library instance. Notes: This library API only provide a basic function of reset. Full function should use the instance in the MdeModulePkg and make sure the depex driver is dispatched.
