When more nodes are added for a uclass the index might go into two or more digits. This means that there are less spaces printed because they are used up by the extra digits. Update the regular expression to allow variable-length spacing between the class name and and index. This was discovered when adding a simple_bus node in test.dts made test_bind_unbind_with_uclass() fail because the index went up to 10. Signed-off-by: Pratyush Yadav <p.yadav@ti.com>
