PCI: alpha: use generic INTx swizzle from PCI core

Browse Source 
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.
