NetBSD/sys/dev/ic/cs4231.c
uwe a05702eaac Rework the driver to add EBus DMA support and improve APC DMA support. 
Audio-related stuff is left almost intact.

* support audiocs at ebus playback and capture
    tested on krups and u5 (thanks, martin)
* make first attempt at supporting audiocs at sbus capture
* nb: full-duplex is not tested
* while here, fix CSAUDIO_MONITOR_MUTE to be of CSAUDIO_MONITOR_CLASS
    i.e. outputs.monitor.mute -> monitor.monitor.mute

Ok by pk, eeh.
