The SH7780 PCI controller supports 3 different ranges of PCI memory in
addition to its PCI I/O window. In the case of 29-bit mode, only 2 memory
windows are supported, while in 32-bit mode all 3 are visible. This
attempts to make the resource handling completely dynamic and to permit
platforms to map in as many apertures as they can handle.

This isn't a real BAR, so prevent any attempts to move it, as we don't
wish to encourage a bus luck by overzealous PCI initialization code.

This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac.
Most of the moving about was done with Sam's directions at:
http://marc.info/?l=linux-sh&m=121724823706062&w=2
with subsequent hacking and fixups entirely my fault.

This patch makes the dreamcast use the recently added declared coherent
memory functions to point out the memory window suitable for dma.
Apart from cleaning up, this gives the dreamcast a proper memory allocator
for pci dma memory.

This cleans up quite a lot of the PCI mess that we
currently have, and attempts to consolidate the
duplication in the SH7780 and SH7751 PCI controllers.

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!
