Adding binman node with target images description can be unwanted feature but as of today there is no way to disable it. Also on size constrained systems it is not useful to add binman description to DTB. Introduce BINMAN_EXTERNAL_DTB Kconfig symbol which allows separate DTB for target from DTB for binman itself.
