This patch adds an fdt_next_node() function which can be used to
iterate through nodes of the tree while keeping track of depth.  This
function is used to simplify the iteration code in a lot of other
functions, and is also exported for use by library users.

This patch adds an fdt_set_name() function to libfdt, mirroring
fdt_get_name().  This is a r/w function which alters the name of a
given device tree node.

This patch adds more documenting comments to libfdt.h.  Specifically,
these document the read/write functions (not including fdt_open_into()
and fdt_pack(), for now).

Update libfdt to commit 8eaf5e358366017aa2e846c5038d1aa19958314e from
the device tree compiler (dtc) project.

Removed:
	fdt_node_is_compatible
	fdt_find_node_by_type
	fdt_find_compatible_node

To ease merge of newer libfdt as we aren't using them anywhere at this time.

Also moved fdt_find_and_setprop out of libfdt into fdt_support.c for the same
reason.

Given the path to a node, fdt_find_and_setprop() allows a property value
to be set directly.
