    nb/intel/sandybridge/gma: add disable function
    
    Issue observed:
    In a multi GPU setup (IGD and PEG) the system still uses the IGD.
    CONFIG_ONBOARD_VGA_IS_PRIMARY has no effect on Sandy/Ivy Bridge.
    
    Test system:
    * Gigabyte GA-B75M-D3H
    * Intel Pentium CPU G2130
    * ATI Radeon HD4780
    
    Problem description:
    The GMA is missing a disable function.
    
    Problem solution:
    Add a GMA disable function. Deactivate PCI device until remaining multi
    GPU issues are resolved. Do not claim VGA decode any more.
    
    Final testing results:
    The system is able to boot using the PEG device as primary VGA
    device.
