    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.
