Dan Williams 6df26700c0 [ARM] 4182/1: iop3xx: fix the ioremap implementation to not remap static ranges
Implement a custom ioremap implementation for iop3xx. This saves
establishing new mappings. It also cleans up the PCI IO resource to be a
physical address rather than a virtual address as Russell pointed out on
the original iop13xx port.
