PCI: x86: use generic pci_swizzle_interrupt_pin()
Use the generic pci_swizzle_interrupt_pin() instead of arch-specific code. Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: hpa@zytor.com Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
