x4x: make preallocated IGD memory a cmos option
This allows to set the preallocated memory for the IGD on x4x
using a cmos option.
If no cmos option is found a default value of 64M is used.
TESTED most options on ga-g41m-es2l with 2G dimm in one slot and 2x2G.
352M also works in contrast with gm45 where it is known to cause issues
with certain ram combinations.
