2f08bfa952 libfdt: Several cleanups to parameter checking
This patch makes a couple of small cleanups to parameter checking of
libfdt functions.

	- In several functions which take a node offset, we use an
idiom involving fdt_next_tag() first to check that we have indeed been
given a node offset.  This patch adds a helper function
_fdt_check_node_offset() to encapsulate this usage of fdt_next_tag().

	- In fdt_rw.c in several places we have the expanded version
of the RW_CHECK_HEADER() macro for no particular reason.  This patch
replaces those instances with an invocation of the macro; that's what
it's for.

	- In fdt_sw.c we rename the check_header_sw() function to
sw_check_header() to match the analgous function in fdt_rw.c, and we
provide an SW_CHECK_HEADER() wrapper macro as RW_CHECK_HEADER()
functions in fdt_rw.c

11abe45c48 libfdt: Remove no longer used code from fdt_node_offset_by_compatible()
Since fdt_node_offset_by_compatible() was converted to the new
fdt_next_node() iterator, a chunk of initialization code became
redundant, but was not removed by oversight.  This patch cleans it up.

d0ccb9b140 libfdt: Trivial cleanup for CHECK_HEADER)
Currently the CHECK_HEADER() macro is defined local to fdt_ro.c.
However, there are a handful of functions (fdt_move, rw_check_header,
fdt_open_into) from other files which could also use it (currently
they open-code something more-or-less identical).  Therefore, this
patch moves CHECK_HEADER() to libfdt_internal.h and uses it in those
places.

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.

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.
