This patch improves the behaviour of the "tumbler/snapper" driver used on
newer PowerMacs during sleep. It properly set the HW mutes to shut down
amplifiers and does an analog shutdown of the codec. That might improve
power consumption during sleep on a number of machines.

This patch hacks the current Alsa snd-powermac driver to add support for
recent machine models with the tas3004 chip, that is basically new laptop
models. The Mac Mini is _NOT_ yet supported by this patch (soon soon ...).
The G5s (iMac or Desktop) will need the rewritten sound driver on which
I'm working on (I _might_ get a hack for analog only on some G5s on the
current driver, but no promise).

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
