How does doing this in the machine driver help here? The machine driver isn't going to be any more coordinated with other machine drivers than the controller is.
There would only be one machine driver loaded at a time. It should provide top-level control over all the audio paths in the Tegra audio subsystem.
OK, so that's not how everyone else has done these isolated controllers... to be honest I'm not convinced that this is something worth worrying about for AC'97 - the clocking is fixed in the spec unless you're being fancy and the chances of anyone being fancy are minimal these days. It's probably more likely to make life miserable for people trying to get AC'97 working than anything else.
But like I say the big thing is a comprehensible changelog.
