Add the latest version of the flatdevtree code and corresponding glue. A phandle table now tracks values returned by ft_find_device(). The value returned by ft_find_device() is a phandle which is really an index into the phandle table. The phandle table contains the address of the corresponding node. When the flat dt is edited/moved, the node pointers in the phandle table are updated accordingly so no phandles kept by the caller become stale. Signed-off-by: Mark A.
