This is, unfortunately, not how we like multiple soc support to be
handled. Instead, the widest constraints are added at the top level
and constrained by the allOf. If none of the names etc are shared, at
least the widest constraints for minItems and maxItems should be able to
be here.

That said, this patch should be squashed with the patch that actually
adds the other device to the binding.

Cheers,
Conor.
