What about, instead of this you add an empty binman node to the other
existing devices? I have tested it with on7xelte and j6lte and it works
as intended.

After this is pulled in, I will submit a patch for binman changes for
those devices, so there's no need of a new .dtsi file.

Alternatively, this series can carry said changes for those devices in a
future revision if you want. Up to you.
