util/ifdtool: Fix ICH Gbe unlock
With coreboot 4.4 switched to "Descriptor mode" for Lenovo T500
it automatically unlocks all flash regions. For Gbe region
the "Requester ID" was hardcoded resulting in *dead* Gbe.
Keep board specific "Requester ID" while unlocking Gbe region.
Allows Lenovo T500 to boot with IFD "Descriptor mode" with unlocked
flash regions.
