[PATCH v3 3/6] binman: Add special subnodes to the nodes generated by split-elf

[Simon Glass]

Special nodes, hash and signature, is not being added to the nodes
generated for each segment in split-elf operation.

Copy the subnode logic used in _gen_fdt_nodes to _gen_split_elf to
ensure special nodes are added to the generated nodes.
