When snd_usb_audio gets probed first, audio mixer doesn't get linked to
the decoder.
Change au0828_media_graph_notify() to handle the mixer entity getting
registered before the decoder.
Change au0828_media_device_register() to invoke
au0828_media_graph_notify() to connect entites that were created prior
to registering the notify handler.
