All the maintained platforms are now in arch/powerpc, so the old
arch/ppc stuff can now go away.

85xx exists in arch/powerpc as well as cuImage support to boot from
a u-boot that doesn't support device trees.

My changes to _tlbie to fix 4xx unfortunately broke 8xx build in a
couple of places. This fixes it.
Spotted by Olof Johansson.

On 4xx CPUs, the current implementation of flush_tlb_page() uses
a low level _tlbie() assembly function that only works for the
current PID. Thus, invalidations caused by, for example, a COW
fault triggered by get_user_pages() from a different context will
not work properly, causing among other things, gdb breakpoints
to fail.
This patch adds a "pid" argument to _tlbie() on 4xx processors,
and uses it to flush entries in the right context. FSL BookE
also gets the argument but it seems they don't need it (their
tlbivax form ignores the PID when invalidating according to the
document I have).

Made the number of TLB CAM entries private and converted the board
consumers to use num_tlbcam_entries which is setup at boot time from
configuration registers. This way the only consumers of the #define
NUM_TLBCAMS are the arrays used to manage the TLB.

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!
