PCI: alpha: use generic INTx swizzle from PCI core
Use the generic pci_common_swizzle() instead of arch-specific code. Note that pci_common_swizzle() loops based on dev->bus->self, not dev->bus->parent as the alpha common_swizzle() did. I think they are equivalent for this purpose. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
