use ac97 default parameters for these ac97 based drivers.

this makes the emulation expansion factor 1 by default since there's no
emulation.  previously the factor was 2 because these drivers emulate
8-bit ulaw playback with 16-bit linear encodings.  having a factor
other than 1 by default creates block size and hiwat/lowat issues
with applications that set the block size and hiwat before other
parameters.
