Log Message:
Add multiple voice support to the ESS Allegro-1 / Maestro-3 family of
audio accelerators.

Mixing is done in hardware by the ASSP, but is limited to 4 simultaneous
channels due to the restricted "minisrc" image that we are currently
working with.

Due to limitations in the audio subsystem, I'm currently attaching multiple
'audio' devices to 'esa', one for each voice. Because of this hack, the
default ESA_NUM_VOICES is 1.
