Clean up the previous:
...
* Separate the interrupt handlers based on which channel (audio1/audio2)
rather than which direction (input/output). Only register the handler for
audio1 on the 1788.
* Since the input sides are actually the same, GC the duplicated code.
* Re-KNF in a bunch of places.
* Make this work again on the 1887 in the Shark.

Add support for the 1788 AudioDrive chip.
...
Some minor cleanup; refer to more registers by macros rather
than raw hex constants.

Remove unused field (sc_ih) in ess_softc (interrupt handlers are kept

in a per-direction structure).

Don't actually touch the hardware in set_params; defer that until we actually
...
start a transfer. Instead, just check that the parameters are valid.
Also, use 16-bit output for u-law and a-law.

Make sure the sample rate is the same on both channels, tracking the change

from one channel to the other if only one is active.

Major cleanup of the ESS driver. It now sorta works. More to come.

A first stab at making the SHARK sound work. It doesn't really work
...
yet, but it probes and makes a noise when used. Stay tuned!

A first stab at an ESS1887 driver. The code is from the SHARK port
...
and needs a lot of polishing. The code compiles (on i386), but is
untested. See ess.c for a TODO list.
