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.
