dtc: Use libfdt endian conversion functions in libfdt
Following on from the last patch, which made dtc use the same endian conversion functions as libfdt, this patch makes ftdump use these functions as well. This brings us down to a single set of endian handling functions in all of dtc and libfdt, so just one place to fix things. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>main
