soc/intel/alderlake/romstage: Update display UPDs based on InternalGfx
Disable all display related UPDs if IGD is not enabled as FSP
don't need to perform display port initialization while IGD itself
is disabled else assign UPDs based on devicetree config.
TEST=Dump FSP-M display related UPDs with IGD enable and disable
to ensure patch integrity.
