This updates the matroxfb code so that it can find the PInS data embedded
in the BIOS on PowerPC cards. The process for finding the data is
different on OpenFirmware cards than on x86 cards, and the code for doing
so was missing.
After patching, building, installing, and booting a kernel, you should grep
for "PInS" in /var/log/messages. You should see two messages in the log:
PInS data found at offset XXXXX
PInS memtype = X
On the GXT135p card I get "31168" and "5". The first value is irrelevant,
but it's presence lets me know that the PInS data was actually found. On a
GXT130p, the second value should be 3. Since I don't have access to that
hardware, if someone can verify that, I will submit a follow-on patch that
rips out all the memtype parameter stuff.

This patch removes some obviously dead code found by the Coverity
checker.

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!
