x4x: add non documented vram sizes
The Intel documtentation, "Intel ® 4 Series Chipset Family" mentions the possibility of 1, 4, 8 and 16M of preallocated memory for the IGD, but does not document this. This allows to set those undocumented values. TESTED on ga-g41m-es2l with 2G dimm in one slot and 2x2G.
