Allow to use OF_OVERLAY_LIST also for the case that the overlays just need be built, e.g. when they will be picked up by binman as artifacts of the final U-Boot image. The IOT2050 boards have such a need when switching to OF_UPSTREAM.

While waiting for the merge of v6.12-rc1-dts and while seeing related but different attempts to address the overlay topic. See the patch in use here:
