This fixes a great many sparse warnings on the fdt and libfdt sources. These are mostly due to incorrect mixing of endian annotated and native integer types. This includes fixing a couple of quasi-bugs where we had endian conversions the wrong way around (this will have the right effect in practice, but is certainly conceptually incorrect). This doesn't make the whole tree sparse clean: there are many warnings in bison and lex generated code, and there are a handful of other remaining warnings that are (for now) more trouble than they're worth to fix (and are not genuine bugs).
