libfdt (new): do_fdt() calls fdt_chosen(..., force=1), where, in
fdt_chosen(), the check to not replace the existing node is governed by
the value of force.

[in gvb's fdt branch, where an 'fdt addr' command is no longer required
prior to bootm ing, do_bootm_linux() calls fdt_chosen(...,force=0),
so maybe it should be changed to force=1.]

about the old code, you're right, I don't see it either - I must have
been remembering running something else that did the rename.  Sorry for
the noise.
