nb/gm45: allow use of 352M preallocated ram for igd

The datasheets on gm45: "Mobile Intel® 4 Series Express Chipset Family"
    mention the possibility of having 352M ram preallocated for the
    integrated graphic device. This only worked fine if the amount of ram in
    the system was 3GB or less. When 4G or more is installed, memory is
    remapped to create a 1GB large pci mmio hole which is not enough and
    creates conflicts when 352M vram is used.

This patch increases the pci mmio hole size on Lenovo x200 to allow
    352M vram to work.

TEST: build and flash on target with 4GB ram or more, use nvramtool to
    set gfx_uma_size to 352M and reboot.
