Move iop33x and iop32x PCI to fixed i/o mapping and remove io.h. This
changes the PCI bus addresses from the cpu address to 0 based. It appears
that there is translation h/w for this, but its untested.
Not sure what to do with io_offset. I think it should always be 0.
AFAICT, PCI setup is skipped if the ATU is already setup.

Mikael Pettersson reported:
The 2.6.28-rc kernels fail to detect PCI device 0000:00:01.0
(the first ethernet port) on my Thecus n2100 XScale box.
There is however still a strange "ghost" device that gets partially
detected in 2.6.28-rc2 vanilla.
The IOP321 manual says:
The user designates the memory region containing the OCCDR as
non-cacheable and non-bufferable from the IntelR XScaleTM core.
This guarantees that all load/stores to the OCCDR are only of
DWORD quantities.
Ensure that the OCCDR is so mapped.

Introduce the arch/arm/plat-iop directory, for code shared between the
iop32x and iop33x, and move the common memory map setup bits there.
