The current tests for fdt_node_check_compatible() test that it returns true on several matching cases, but don't test that it actually returns false on some non-matching cases, which isn't great coverage. Add some basic tests to address that. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
