Make sure MC vram map is >= pci aperture size

Ok, I think I found the root cause in this bug.  The vram map in the memory
controller needs to be >= the pci aperture size.  For the systems here, the
vram size is 64 MB and the aperture size is 128 MB so the vram map in the mc
needs to be at least 128 MB.  However, it's getting set to 64 MB.
