Subject: [PATCH] pci: disable MSI on VIA K8M800

MSI delivery from on-board ahci controller doesn't work on K8M800.  At
this point, it's unclear whether the culprit is with the ahci
controller or the host bridge.  Given the track record and considering
the rather minimal impact of MSI, disabling it seems reasonable.

Maybe we should whitelist working ones from via rather than the other
way around.  :-(
