[PATCH v5 1/2] Makefile: dtc: update, build the libfdt target

[Claudio Fontana]

dtc submodule update, now call the libfdt target from the new
dtc Makefile, which has been changed to not require bison, flex, etc.
This removes warnings during the build.

scripts/ symlink and tests directory creation are not necessary,
and neither is calling the clean rule explicitly.
