pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile
The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.
Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.
I also rewrote the Makefile in a cleaner Kbuild style.
The scripts from the upstream have been moved as follows:
lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped
The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.
