This patch updates the PowerMac cpufreq driver.  It depends on the addition
of the suspend() method (my previous patch) and on the new flag I defined
to silence some warnings that are normal for us.

It fixes various issues related to cpufreq on pmac, including some crashes
on some models when sleeping the machine while in low speed, proper voltage
control on some newer machines, and adds voltage control on 750FX based G3
laptops.

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!
