There's a balance to be struck between duplication and readability. If you insert this board-specific code into a generic code path, that generic code path becomes difficult to read given the extra #ifdef guards etc. If you're really worried about duplicating code you can move the two libfdt calls into a separate function and call that function from each of the boards that need it.
