Several tests (truncated_property, truncated_string, truncated_memrsv and unterminated_memrsv), rather than loading their example dtb from a file, instead link directly to trees.o and get the data from directly in their own data segment. This was a clever trick once, but it's kind of awkward, and makes it harder to generalise how we generate those trees. Change them to load their example data from file, like most of the tests already do. Assisted-by: Claude:claude-opus-4-6 Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
