c067afaa06 unfinished sblive driver, playback/mixer only for now - not enabled in 
conf/files

i don't seem to be clearing the cache right resulting in a short initial
burst of noise, despite doing the same as creative and alsa.  i'm committing
now so more eyes can pore over the code.

57376530f0 split up ess and sb code 
rewrite ess mixer to use native registers
rewrite play/rec code to use more accurate timer when available
add code to use audio2 for playback, but disable it as no irqs are generated

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

d8b47cbb70 Stop isadma from abusing the B_READ, B_RAW and B_WRITE flags. 
Define ISADMA_{READ,WRITE,RAW} macros with the same numeric
values as the B_{READ,WRITE,RAW} and use them instead throughout.

1a7d73a130 Partial fix: the following patch correctly configures the card for dual 
channel DMA. The problem was that the SDC bit (0x04) can only be set in
the MCE state.

a3a2b1e1b2 Note the PnP id's for the NMX2210 next to the id's where they are used. 
The pnpbios doesn't supply a description in the case we've seen so
supply one.

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.

f2410ff244 kludge to fix the end-of-sample repeating bug. i don't know why it happens; 
none of my hw does it, but this should fix it for now.

10b23f4c02 don't complain about bad intrs unless we get 1000 of them consecutively 
whilst we are playing or recording.  since we should irq ~20 times/sec when
active, this should never trigger.  in theory.  if it never does trigger,
the check will be removed.

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.
