Work-in-progress driver for the HP ``Audio1'' device found on the HP 9000/425e

(hp300) and the HP9000/705 and 9000/710 (hppa). 8-bit mono, 8KHz, no surprise
since it is based upon a digital phone chip.
Tested on 425e only so far, and playback only; configured in, but disabled,
on hppa kernels until there are positive test reports (I am not sure the
interrupt assignment on hppa is correct).
And now people no longer can joke about audio on hp300.

+.Cd "arcofi* at dio?"
+.Cd "arcofi* at gsc?"
+.Cd "audio*  at arcofi?"
+.Sh DESCRIPTION
+The
+.Nm
+driver supports the HP
+.Dq Audio1
+audio devices, based upon the Siemens PSB2160
+.Dq ARCOFI
+codec, to implement the audio device interface described in
+.Xr audio 4 .
+.Pp
+This device is found onboard HP 9000 workstations models 425e, 705 and 710.
+.Pp
+The
+.Nm
+is limited to a phone-quality mono, 8 bits, 8000 KHz sound.
+.Sh SEE ALSO
+.Xr ioctl 2 ,
+.Xr audio 4 ,
+.Xr dio 4 ,
+.Xr gsc 4
+.Xr intro 4
+.Sh HISTORY
+.Ox
+support for
+.Nm
+first appeared in
+.Ox 5.1 .
+.Sh CAVEATS
+Due to the
+.Dq ARCOFI
+chip being designed to build phones, it is not possible to unmute the
+.Sq line in
+channel while muting
+.Em all
+output channels.
+Attempting to do this will cause all channels (input and output) to be unmuted.
