of: Add KUnit test to confirm DTB is loaded
Add a KUnit test that confirms a DTB has been loaded, i.e. there is a
root node, and that the of_have_populated_dt() API works properly. We
skip the test when CONFIG_OF_EARLY_FLATREE=n because in that case we
know architecture code hasn't called unflatten_(and_copy_)?device_tree()
which would populate some sort of root node.
