A phandle in an overlay is not supposed to overwrite a phandle that already exists in the base dtb as this breaks references to the respective node in the base. So add another iteration over the fdto that checks for such overwrites and fixes the fdto phandle's value to match the fdt's. A test is added that checks that newly added phandles and existing phandles work as expected.
