nb/intel/gm45/gma: Probe PCI resource once and first

The PCI resource should only be probed as part of the device
.init process. We can simply do that first and know that we
can use the global `gtt_res` from then on.

This simplifies the signature of gm45_get_lvds_edid_str(), and
makes changes to the API user (lenovo/x200) necessary.
