This change adds an initial IPMI driver for powerpc OPAL firmware. The
interface is exposed entirely through firmware: we have two functions to
send and receive IPMI messages, and an interrupt notification from the
firmware to signify that a message is available.

The default probing can cause problems with some system, slow booting,
extra CPU usages, etc.  Turn it off by default and give a config option
to enable it.

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!
