nb/intel/i945: Switch back from V4 to V3 resource allocator to fix hangs

On the Lenovo T60 (TYPE 2007 with dedicated ATI/AMD graphics card) with the
resource allocator v4 the system 99 percent of the time hangs decompressing the
payload or a little later. coreboot runs the VGA Option ROM, as the GRUB
payload is used.

Sometimes it halts also a little later.
