[BUGFIX] Use DriverInterface instead AbstractDriver for method signature

FAL drivers are not obligated to extend the AbstractDriver but only
to implement the DriverInterface. Having custom drivers that are not
based on AbstractDriver (because they are f.e. non hierarchical)
currently causes an Exception because PreviewProcessing expects an
instance of AbstractDriver as method argument.

This patch changes te signature from AbstractDriver to DriverInterface.
