- Add a new flag to the PCI-PCI driver to disable MSI on devices behind the
bridge if it doesn't pass MSI messages up correctly. We set the flag
in pcib_attach() if the device ID is disabled via a PCI quirk.
- Disable MSI for devices behind the AMD 8131 HT-PCIX bridge. Linux has
the same quirk.
Tested by: no one despite repeated calls for testers
