Catch up vs_set_params() to recent MI audio (after in-kernel mixer).

Browse Source 
Before that, MD part had to support all encodings I'd like to support,
but currently it's no longer necessary.  The hardware is
4bit/1ch/15.6kHz ADPCM but it behaves as 16bit/1ch/16.0kHz PCM.

For audio.c < 1.362, the device attach succeeded and playback is
still working.
For audio.c >= 1.363, the device attach fails again.
It does not work yet but I commit it for milestone.
