ARM: iop3xx: use fixed PCI i/o mapping
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.
