ae0b5908de libfdt: Add and use a node iteration helper function.
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.

9eaeb07a71 libfdt: Add fdt_set_name() function
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.

aec7135bc3 libfdt: Add more documentation (patch the seventh)
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).

a3c2933e02 Removed some nonused fdt functions and moved fdt_find_and_setprop out of libfdt
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.

1a861169bc Replace fdt_node_offset() with fdt_find_node_by_path().
The new name matches more closely the kernel's name, which is also
a much better description.

6679f92995 libfdt: Make fdt_check_header() public
Changed _fdt_check_header() to fdt_check_header() and made it part of
the interface - it is a useful routine.

Also did some asthetics cleanup to the include files (headers).
