Move the caller's pointer back to match the change in the region's start,
rather than alter a byte of the device tree's content.

The ft_reorder() function may change the start of the region of interest,
so the pointer provided by the caller into that region must be fixed up
to still point to the same datum.

Currently, if ft_get_phandle() is passed NULL it will allocate an entry
for it and return a non-NULL phandle. This patch makes it simply pass
the NULL through.

This name better reflects what the function does, which is to
look up the phandle for an internal node pointer, and add it to the
internal pointer to phandle table if not found.

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.
