PCI: quirk disable MSI on via vt3351
The Via VT3351 APIC does not play well with MSI and unleashes a flood
of APIC errors when MSI is used to deliver interrupts. The problem
was recently exposed when the atl1 network device driver, which enables
MSI by default, stimulated APIC errors on an Asus M2V mainboard, which
employs the Via VT3351.
See http://bugzilla.kernel.org/show_bug.cgi?id=8472 for additional
details on this bug.
