PCI: re-enable onboard sound on "MSI K8T Neo2-FIR"
On the "MSI K8T Neo2-FIR" board the BIOS disables the onboard
soundcard, if a second PCI soundcard is present.
This patch sets the korrect register bit to enable the onboard sound.
Removed old code in /drivers/pci/quirks.c that only checks for the
PCI-ID and fires on any Board with VIA 8237.
New code in /arch/i386/pci/fixup.c checks the DMI-tables and only runs
on the specific board.
