Just checked in AOSP/master, seems like the feature is there, it's
called "dump".

    $ mkdtimg dump dtbo.img --dtb filename

For details see:

    $ mkdtimg help dump

    mkdtimg dump <image_file> (<option>...)

    options:
      -o, --output <filename>  Output file name.
                               Default is output to stdout.
      -b, --dtb <filename>     Dump dtb/dtbo files from image.
                               Will output to <filename>.0, <filename>.1, etc.

You can convert dtb to dts further, using "dtc" tool.
