[POWERPC] Do not write virq back to PCI config space
- Drivers will not rely on the PCI config space value, as they've
already been conditioned to rely on the irq field in "struct pci_dev".
- The virq value may not be < 256 as it has been remapped.
- The PCI config space should reflect the hardware configuration, which
is not being changed. We are only creating a virtual irq mapping that
exists in the kernel only. One would never expect the PCI hardware to
generate the "virq" interrupt.
