libfdt: Use correct property format 

Since its beginning, libfdt has used an incorrect definition of the
format for a property, putting the name offset before length, rather
than the other way around as described in booting-without-of.txt.

This corrects the error, making libfdt actually produce and use trees
which are compatible with the kernel and dtc.
