drm/radeon/kms: fix quirk for MSI laptop
The line mux for the connector in the bios tables is used for enumerating drm connectors. Since this laptop has a quirk where the same line much is listed for both VGA and LVDS, the connectors get combined. Setting the line mux on LVDS to an unused value prevents both encoders from being combined into the same connector. This should fix bko bug 13720.
