svn commit: r292644 - head/tools/tools/nanobsd/embedded

[Warner Losh]

Thanks Ian. I'll adjust. The dtb files don't hurt anything, and it would be
extra config to have
some platforms do it and not others (something I'm trying to avoid). I'll
document it for later.
However, if there's no point to the uenv file, that's easy to just remove.
