libfdt: Add and use a node iteration helper function.
This patch adds an fdt_next_node() function which can be used to iterate through nodes of the tree while keeping track of depth. This function is used to simplify the iteration code in a lot of other functions, and is also exported for use by library users. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
