The early console implementations are the same all over the place. Move
the print function to kernel/printk and get rid of the copies.

This adds some VBR sanity checks in the sh_bios code to ensure that the
BIOS VBR is in range before blindly trapping in to it. This permits
boards with varying boot loader configurations to always leave support
for sh-bios enabled and it will just be disabled at run-time if not
found.

Now that the sh-sci earlyprintk is taken care of by the sh-sci driver
directly, there's no longer any reason for having a split-out
early_printk framework. sh_bios is the only other thing that uses it, so
we just migrate the leftovers in to there. As it's possible to have
multiple early_param()'s for the same string, there's not much point in
having this split out anymore anyways, particularly since the sh_bios
dependencies are still special-cased within sh-sci itself.

This moves the VBR handling out of the main trap handling code and in to
the sh-bios helper code. A couple of accessors are added in order to
permit other kernel code to get at the VBR value for state save/restore
paths.

With the reworked kgdb support, we always detach and reinitialize the
stub. This was mostly a feature for handoffs between sh-ipl+g and the
kgdb stub, but virtually no sh-ipl+g versions ever had this working
right in the first place.
Given that the sh-ipl+g stubs in general use today don't even support
the GDB stub, and we have already killed off the special casing in the
sh-sci serial driver, kill off this now unused symbol too.

allmodconfig generates a lot of interesting code, a lot of the
generated symbols we've never exported before, so this fixes
those up. Verified with both GCC3 and GCC4 toolchains.

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!
