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.

[POWERPC] Consolidate cuboot initialization code

The various cuboot platforms (i.e. pre-device tree aware u-boot for
83xx, 85xx and Ebony) share a certain amount of code for parsing the
boot parameters. To a certain extent that's inevitable, since they
platforms have different definitions of the bd_t structure. However,
with some macro work and a helper function, this patch improves the
situation a bit.

In the process, this fixes a bug on Ebony, which was incorrectly
handling the parameters passed form u-boot for the command line (the
bug was copied from 83xx and 85xx which have subsequently been fixed).

The uppermost part of memory is where u-boot puts the stack, so don't
include that in the heap. It's not currently causing problems, as the
current code allocates from the bottom of the heap, but this will keep
things from potentially breaking if a future implementation were to
allocate from the top.
