[RFC]drivers/intel/gma: Add common devicetree structure

Add a platform independend structure to hold all required GPU related
information. Every field has a clear description and usage.
Instead of using the northbridge device, the new field will be attached
to the GMA device.

To be used on all Intel platforms.
