[POWERPC] Cell "Spider" MMIO workarounds
This patch implements a workaround for a Spider PCI host bridge bug where it doesn't enforce some of the PCI ordering rules unless some manual manipulation of a special register is done. In order to be fully compliant with the PCI spec, I do this on every MMIO read operation.
