Fix this by making that variable a pointer and having the bus drivers set the operations prior to registering. This is not a particularly good or nice approach but it avoids blocking multiplatform and a real fix involves fixing the fairly deep problems with AC'97 support - we should be converting it to a real bus.

For example: ERROR: "soc_ac97_ops" [sound/soc/codecs/snd-soc-wm9712.ko] undefined! To fix, export soc_ac97_ops to modules.
