You're already creating a new binding when changing the max-items.
So when we change that again later, in theory you'd need to support both
cases (with and without clock-names)

So I'd really prefer to get the binding right the first time and
identifying multiple clocks by clock-names instead of an implicit ordering
is way better in the long run as well.
