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.
