PCI quirk: RS780/RS880: disable MSI behind the PCI bridge

The missing initialization of the nb_cntl.strap_msi_enable does not
seem to be the only problem that prevents MSI, so that quirk is not
sufficient to enable MSI on all machines.  To be safe, disable MSI
unconditionally for the internal graphics and HDMI audio on these
chipsets.

[rjw: Added the PCI_VENDOR_ID_AI quirk.]
