powerpc/pci: Don't configure PCIe settings when PCI_PROBE_ONLY is set
We don't want to configure PCI Express Max Payload Size or Max Read Request Size on systems that set that flag. The firmware will have done it for us, and under hypervisors such as pHyp we don't even see the parent switches and bridges and thus can make no assumption on what values are safe to use.
