These methods are no longer needed because SystemServer is able to populate the DevFS on its own. Device absolute_path no longer assume a path to the /dev location, because it really should not assume any path to a Device node. Because StorageManagement still needs to know the storage name, we declare a virtual method only for StorageDevices to override, but this technique should really be removed later on.
