The chip is only rated for 44.1KHz, and will not record faster that 46.794KHz,
...
so adjust ESS_MAXRATE. ESS_MINRATE was also wrong, not that anyone cares.

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.

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

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.
