dtc: Use the same endian-conversion functions as libfdt

Currently both libfdt and dtc define a set of endian conversion macros
for accessing the device tree blob which is always big-endian.  libfdt
uses names like cpu_to_fdt32() and dtc uses names like cpu_to_be32 (as
the Linux kernel).  This patch switches dtc over to using the libfdt
macros (including libfdt_env.h to supply them).  This has a couple of
small advantages:
	- Removes some code duplication
	- Will make conversion a bit easier if we ever need to produce
          little-endian device tree blobs.
	- dtc no longer needs to pull in netinet/in.h simply for the
          ntohs() and ntohl() functions
