Maybe a #define instead of using magic numbers?

I was thinking about that, actually we have much more magics in
r600_audio.c. Many masks and shifts are not defined. However I would
have to just guess some names which is acceptable, but I believe we
will get real names finally released soon. Alex wrote fixes for audio,
patches are waiting for IP review.

In this situation I prefer to just leave it as is for now. It's
probably not worth of cleaning that if this will be over-cleaned
anyway.
