Before we had the support for card table based setup you'd had to register 
them in chunks, because the components became available one after another 
and you couldn't register DAPM elements for one component in the callback of 
another one. When using the table based setup the widgets are registered 
before all components are registered and the routes are registered after all 
the components have been registered.
