Clean up some of the open-coded data structure references by providing a
function to return a pointer to the tree's root node. This is only used
in high-level functions trying to access the root of the tree, not in
low-level code that is actually manipulating the data structure.

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.
