It was getting a little big, ugly and a primary source for merge conflicts.
Also the old method was a bit too forgiving in that the workaround did
default to off, so now there is an explicit #error forcing platform
maintainers to think if they should enable a workaround for a particular
platform.

Before this patch, when a platform needed to customize one constant in
spaces.h, they need to redefine all of them.
Now they can just redefine one constant and include the generic file
header at the end:
#include <asm/mach-generic/spaces.h>
This patch doesn't allow to redefine CAC_BASE, IO_BASE and UNCAC_BASE
for 32 bits platforms because there's no need to do so.
This will avoid some macro duplications. It's important specially if
we'll add complex macros.

Platforms will now have to supply a function dma_device_is_coherent which
returns if a particular device participates in the coherence domain. For
most platforms this function will always return 0 or 1.

Keeping in accordance with other machines, IP27 and IP32 lack a few
macros. IP27 lacks cpu_has_4kex & cpu_has_4k_cache macros while IP32
lacks just the cpu_has_4k_cache macro.

1. Move ioswab*() and __mem_ioswab*() to mangle-port.h. This gets rid
of CONFIG_SGI_IP22 from include/asm-mips/io.h.
2. Pass a virtual address to *ioswab*(). Then we can provide
mach-specific *ioswab*() and can do every evil thing based on its
argument. It could be useful on machines which have regions with
different endian conversion scheme.
3. Call __swizzle_addr*() _after_ adding mips_io_port_base. This
unifies the meaning of the argument of __swizzle_addr*() (always
virtual address). Then mach-specific __swizzle_addr*() can do every
evil thing based on the argument.

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!
