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
