f314f3dad2 add module metadata. this is a hack, sound drivers will eventually present a
bus to which pcm, mixer, etc will attach.

39004e693d update the ac97 layer:
* add a callback for initialising the mixer interface
* support ac97 2.1 variable rate audio feature

fix ac97-using drivers for the above

add suspend/resume support for neomagic

8f7076b8ff The pointer of the serial FIFO in the DSP seems to make an error
upon starting/stopping the DSP. Correct the pointer in addition
to clearing the FIFO.

f259d7eed5 - Handle an interrupt for csa primarily in the bridge driver,
then invoke the children. As the value of HISR can be read
  only once, pass the HISR to the children via struct
  csa_bridgeinfo, stored in the ivars of them.
- Clear the contents of serial FIFO upon stopping the DMA for
  playing. This may eliminate buzz on playing. Experimental.

c2af6f650c Update for pnp adjustments regarding NPNP.
Also, optimize out a mess of #if's that were duplicating work already
done by config(8).  For example, if a file is marked as
"dev/sound/pci/foo.c optional pcm pci" then it's only added if pcm *and*
pci are present, so #if NPCM > 0 and #if NPCI > 0 are totally redundant.
A bit more work is still needed.

Discussed with: cg (a few weeks ago)
