    intel/gma: Fix vbt generation
    
    The log shows the following error on systems that use the
    native gfx init. The error isn't show using VBIOS blob:
    GET_VBIOS: aa55 8086 0 3 0
    VBIOS not found.
    
    Don't shift the class-code, as it's already shifted by the PCI layer.
    
    Not tested using native gfx init.
