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.
