Subject: VIA quirk fixup, additional PCI IDs

An earlier commit (75cf7456dd87335f574dcd53c4ae616a2ad71a11) changed an
overly-zealous PCI quirk to only poke those VIA devices that need it.
However, some PCI devices were not included in what I hope is now the full
list.  Consequently we're failing to run the quirk on all machines which need
it, causing IRQ routing failures.

This should I hope correct this.

Thanks to Masoud Sharbiani <masouds@masoud.ir> for pointing this out
and testing the fix.
