Subject: Reworked audio drivers for Atari platform
These are reworked audio drivers for the Atari platform.
Previous drivers were missing some features:
- Test external clock plugged to DSP port on Atari Falcon 030.
- Ability to select internal or external clock.
So now, I generate a list of frequencies available, with the master clock
and predivisor to use. One big caveat to this: I do not have an external
clock, so I hope it works.
