Replace fdt_next_node() with depth tracking with fdt_for_each_subnode()
which has been available for some time.
This also fixes a latent bug where the default configuration was being
read from the wrong node offset. It happened to work before because
noffset ended up at the right value after the images loop.

fit: Improve and test the code to print FIT info
The code for printing information about FITs is fairly old and not that
easy to maintain. It also lacks tests.
This series adds some tests, moves the code into its own file and then
adds a series of helpers to deal with the intricacies of printing each
item.
This provides a binary-size reduction of about 320 bytes on aarch64.
