Nodes in the base fdt that do not have phandles cannot currently be referenced
in overlays; we can target them for an overlay, but we cannot use them as a
reference in another property if needed. This is quite limiting for some
use-cases where you're needing cross-references that don't currently exist in
the base.

fdt

phandles
