Note that this isn't signed off. I think we should get Ron's dts
changes in first and then I will resubmit this patch.
I have removed CONFIG_VIDE0_MB and set the Geode graphics memory size
through the geode northbridge pci dts. I think that this is a better way
to handle this value. To do this I had to move some functions and
structures around.
Comments?
