Patch from Lennert Buytenhek
Remove the ixdp2x01 cs89x0 hack from ixp2000's io implementation.
Since the cs89x0 driver has been made properly aware of the odd way
the cs89x0 is hooked up on the ixdp2x01, we don't need this hack
anymore.

Including asm/hardware.h into asm/io.h can cause #define clashes
between platform specific definitions and driver local definitions.

Patch from Lennert Buytenhek
The later ixp2000 models don't need the PCI I/O workaround that we
currently perform. Add a config option to disable the workaround,
and panic on boot if a kernel without the workaround is booted on a
buggy chip. As only pre-production ixp2000s need the workaround,
the default is for it not to be configured in.

Patch from Lennert Buytenhek
A number of ixp2000 models have a bug where the byte lanes for PCI I/O
transactions are swapped. We already work around this in our versions
of {in,out}{b,w,l}, but we also need to perform these workarounds in a
custom implementation of the new iomap API, provided in this patch.

Patch from Lennert Buytenhek
Two macros that are used on the ixp2000 to fixup byte lane enables
for I/O space accesses, align{b,w}, use their arguments without
parenthesizing them.

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!
