pci_bridge: Remove duplicate IRQ swizzle function pci_bridge_dev_map_irq_fn() is identical to pci_swizzle_map_irq_fn(), which is now the default for all PCI bridges. We can therefore remove this function and the pci_bridge_map_irq() call that used it. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
