This patch removes the last usage of linux/ac97_codec.h by renaming ac97 registers to use sound/ac97_codec.h definitions. This will enable us to remove linux/ac97_codec.h.
Not even compilation tested.

Hi all,
This patch is important so we can remove linux/ac97_codec.h usage. Since this driver is mips related, I can't test it until I install a mips toolchain. If someone can compile this for me, or even test it with real hardware I think it would be better. If not then I can install a mips toolchain and compile it myself, but I won't be able to test it on real hardware.
This patch should be treated with carefully and be applied only if someone manages to test it.
A slight concern by this change is that the driver includes sound/ac97_codec.h although it's based on OSS framework. sound/ac97_codec.h is the header for ALSA ac97 structs, and this can't be mixed up with OSS.
If the intention is only about AC97 register definition, we may split ac97_codec.h into ac97_regs.h and ac97_codecs.h where the former contains only the register definitions (thus framework-neutral) and the latter includes the former.
Yes, splitting sounds good to me. It could be useful for other ac97 drivers (e.g. em28xx).
On a second thought, I'm not sure splitting the header is the best way to proceed. Since swarm just uses some AC97 register definition maybe we could just duplicate those (less than ten) macros in swarm c file.
It's a less intrusive aproach and it allows us to remove the unused linux/ac97_codec.h.
I'm OK in both ways.
Takashi
