[ARM] 4077/1: iop13xx: fix __io() macro
Since iop13xx defines the PCI I/O spaces with physical resource addresses
the __io macro needs to perform the physical to virtual conversion. I
incorrectly assumed that this would be handled by ioremap, but drivers
(like e1000) directly dereference the address returned from __io.
