binman: Include also subnodes in generator nodes

This allows to prefill fdt and config nodes with hash and signature
subnodes. It's just important to place the child nodes last so that
hashes do not come before the data - would be disliked by mkimage.

binman: test: Rename 172_fit_fdt.dts to 170_fit_fdt.dts

Currently there are 2 binman test cases using the same 172 number.
It seems that 172_fit_fdt.dts was originally named as 170_, but
commit c0f1ebe9c1b9 ("binman: Allow selecting default FIT configuration")
changed its name to 172_ for no reason. Let's change it back.
