Log Message:
Updates PR kern/32651

The eap driver now makes use of the MIDI UART tx interrupt available on
the Ensoniq chips.  A test with nominally 20 seconds of continuous transmit
data went from 26 s real / 25 s system to 22 s real / 0.16 s system.
Implementation is quite simple, and anyone who knows any of the other
MIDI UART chips well enough to get a tx interrupt out of it would do a
world of good by updating their drivers similarly.

Anyway, scratch one off the kern/32651 todo list.

Also added a documentation reference to the ES1373 datasheet, and added
more 1371- and 1373-specific #defines in eapreg.h.  Enough there now that
anyone who wanted to play with the S/PDIF capability on the 1373 could
begin to do that.
