LIBFDT: use memmove() instead of memcpy()
PATCH 1/1 LIBFDT: use memmove() instead of memcpy()
This is partial patch from the DTC/libfdt
commit 67b6b33b9b413a450a72135b5dc59c0a1e33e647

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().

After comparing dtc/libfdt source to our libfdt source, I found we were missing this partial patch. The rest of the patch is not applicable.
