pp->io_base which is the input of the outbound IO address translation
unit should be the cpu address, it was programmed wrongly to realio
address.

We should pass global_io_offset rather than sys->io_offset to
pci_ioremap_io, so we map the new window into the first available spot
in the Linux view of the I/O space.

We must also pass cpu address instead  of realio address to
pci_ioremap_io.

This patch fixes above issue. It has been tested with Lecroy PTC in AIC
mode and Pericom PI7C9X2G303EL PCIe switch, which does not work
otherwise.
