Add libfdt unit test cases

This patch incorporates the standalone libfdt unit tests written by Andre
Przywara into the unit test framework.  These tests use DTB files to
exercise the functions in libfdt and fdt_wrappers.c to ensure that they work
correctly.

Several of these DTBs cannot be supplied in this repository due to license
restrictions, they are found in the Linux kernel source tree and in the
trusted firmware a source tree.  A script has been provided to build these
DTB files and place them in the correct location to be used and can be
found in tests/lib/fdt/device_trees, it requires the two source trees to
be provided as arguments.

At some point we'd like to include DTS files in this repository to make
things easier but for now they are external dependencies.
