2a9d2d97d3 [POWERPC] wrapper: Treat NULL as root node in devp_offset; add devp_offset_find()
Many operations, as currently used in the wrapper, assume they can
pass NULL and have it be treated as the root node.  However, libfdt-wrapper
converts NULL to -1, which is only appropriate when searching for nodes,
and will cause an error otherwise.

754e5f3f3a [POWERPC] wrapper: Rename offset in offset_devp()
fdt_wrapper_create_node passes a variable called offset to offset_devp(),
which uses said parameter to initialize a local variable called offset.

Due to one of the odder aspects of the C language, the result is an
undefined variable, with no error or warning.

2f0dfeaa84 [POWERPC] Use embedded libfdt in the bootwrapper
This incorporates libfdt (from the source embedded in an earlier
commit) into the wrapper.a library used by the bootwrapper.  This
includes adding a libfdt_env.h file, which the libfdt sources need in
order to integrate into the bootwrapper environment, and a
libfdt-wrapper.c which provides glue to connect the bootwrapper's
abstract device tree callbacks to the libfdt functions.

In addition, this changes the various wrapper and platform files to
use libfdt functions instead of the older flatdevtree.c library.
