set vram on gm45 to 352M

This patch enables all vram sizes and sets the default to 352M for

Normally users have to clear their vram for this to happen. using
"nvram -c random"

But there a 2 better option:
coreboot provides to always load the defaults in its menuconfig
update the flashscript to reset cmos

+Subject: [PATCH 1/2] 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.
+
+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.
