For the aoa bits this ends up having two "Apple Onboard Audio driver"
bits which is a bit confusing. How about this instead? SND_AOA was
pretty much a generic symbol to start with since it will cause snd-aoa
to be compiled but is pretty much useless on it's own. This hence makes
the core bits an invisible symbol.
