The revert of 991de2e59090 ("PCI, x86: Implement pcibios_alloc_irq()
and pcibios_free_irq()") causes a problem for IOAPIC hotplug. If
a device under the IOAPIC doesn't call pci_disable_device(), then
the hot-removal of the IOAPIC causes kernel stack dump.

This patchset can fix the problem. IOAPIC hot-removal works correctly
after applying this patchset.

v2: 0001 Fixed a missing stub function causing compiling error on i386 
    0002 Fixed a typo on the subject line.

  x86/PCI: Implement pcibios_release_device to release IRQ from IOAPIC
  x86/ioapic: Split IOAPIC hot-removal into two steps
