[U-Boot] [PATCH] Clean up libfdt.h includes

[Jerry Van Baren <gvb.uboot@gmail.com>]

The libfdt.h file is the definition file for libfdt.  It is unnecessary
to include other fdt header files (the necessary ones are pulled in
by libfdt.h).

This comes from discussion on the Device Tree email list that <libfdt.h>
is *the* user interface definition.

FWIIW, I proposed removing the redundant #includes in the libfdt source
too, but it hasn't been accepted by David Gibson yet.  He is open to the
concept but I have not pushed it forward to the point where he says
"yes" or "no".  I have the patch, but am holding it for when dtc/libfdt
accepts it (or not).

Best regards,
gvb
