Only if there are multiple Additional Standard Extensions is it needed to have an underscore. The dt-binding does not validate that a multi-letter extension is canonically ordered, as that'd need an even worse regex than is here, but it should not fail validation for valid ISA strings. Allow the first Z multi-letter extension to appear immediately prior after the single-letter extensions.
