siemens/mc_tcu3: Don't try to init unsupported panel type 

The LCD panel type is read using 4 GPIOs. Of these 16 possible
combinations only 5 are supported right now. If the GPIO setting encodes
an unsupported panel type, there will be no matching hwinfo.hex in cbfs.
Therefore it makes no sense to try to initialize the DisplayPort-2-LVDS
converter. Leave the function instead in this case.
