Why is this not being done in the commit adding the jhb100 in the first
place?

This can just be "maxItems: 5", since minItems is set outside the
conditional to 5.

Remove these constraints, since they don't do anything more than the
outside ones do.

Can't you just leave this list outside the conditional section, and add
the extra item to the end? The only difference appears to be the
sgmii_rx clock, and it's at the end.

I'm also not really convinced that this flexibility is required, unless
there are some controllers on the platform that do not support sgmii.
