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.
