  Log:
  Add a first pass at a way to blacklist MSI on systems where it doesn't
  work:
  - A new PCI quirk (PCI_QUIRK_DISABLE_MSI) is added to the quirk table.
  - A new pci_msi_device_blacklisted() determines if a passed in device
    matches an MSI quirk in the quirk table.  This can be overridden (all
    quirks ignored) by setting the hw.pci.honor_msi_blacklist to 0.
  - A global blacklist check is performed in the MI PCI bus code by checking
    to see if the device at 0:0:0 is blacklisted.
