PCI: add pci_common_swizzle() for INTx swizzling
This patch adds pci_common_swizzle(), which swizzles INTx values all the
way up to a root bridge.
This common implementation can replace several architecture-specific
ones. This should someday be combined with pci_get_interrupt_pin(),
but I left it separate for now to make reviewing easier.
