PPC: e500: implement PCI INTx routing
This patch adds pci pin to irq_num routing callback.
This callback is called from pci_device_route_intx_to_irq to
find which pci device maps to which irq.
This fix is required for pci-device passthrough using vfio.
Also without this patch we gets below prints
"
PCI: Bug - unimplemented PCI INTx routing (e500-pcihost)
qemu-system-ppc64: PCI: Bug - unimplemented PCI INTx routing (e500-pcihost) "
and Legacy interrupt does not work with pci device passthrough.
