    The patch also fixes one genuine bug caught by valgrind -
    _packblocks() in fdt_rw.c was using memcpy() where it should have been
    using memmove().

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.

Modify libfdt/Makefile to conditionally compile the *.c files based
on the board config.

This change is in preparation for condtitionial compile support in the
build system.  By spliting them all into seperate lines now, subsequent
patches that change 'COBJS-y += ' into 'COBJS-$(CONFIG_<blah>) += ' will
be less invasive and easier to review

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

Also removes the special case root path detection in cmd_fdt.c since it
is no longer necessary.

The new name matches more closely the kernel's name, which is also
a much better description.

This is the way u-boot reduces configured-out code.  At Wolfgang
Grandegger and Wolfgang Denk's request, make libfdt conform.

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).

Enhanced the formerly private function _fdt_next_tag() to allow stepping
  through the tree, used to produce a human-readable dump, and made
  it part of the published interface.
Also added some comments.

Changes to David Gibson's original source to fit into u-boot's
environment.  No functionality changes.

This adds the applicable libfdt source files (unmodified) and a README
to explain where the source came from.
