[PATCH 01/17] bootwrapper: Make ft_create_node() pay attention to the parent parameter.

[Scott Wood <scottwood@freescale.com>]

Previously, ft_create_node() ignored the parent parameter, and instead
created the new node as a child of the root node.  The node is now
created as a child of "parent".

This patch is the same as before, but with a more verbose commit message,
as requested by David.
