libfdt: Export overlay_apply_node() as fdt_overlay_apply_node()
This function is useful to merge a subset of DT into another DT, for
example if some prior-stage firmware passes a DT fragment to U-Boot
and U-Boot needs to merge it into its own DT. Export this function
to permit implementing such functionality.
