gm45: enable setting all vram sizes from cmos
Setting the size of the preallocated memory for the igd is done using a cmos parameter, gfx_uma_size. This was limited to a subset of all available sizes, that were already implemented elsewhere in the northbridge code. What this does is change the cmos parameter to 4 bits instead of 3 bits to accomodate all vram sizes. It also adds a sane default of 32mb that already was in place. The northbridge code that reads this cmos parameter is also changed for this new cmos settings. 352M is disabled since it causes issues on systems with 4GB or more ram. TEST: Build, flash target. Clear cmos by corrupting the checksum (nvramtool -c something). Set a desired value in gfx_uma_size using nvramtool. "dmesg | grep stolen" to see what is actually allocated.
