I may not under this property very well. What exactly does this line
say ? Asking as required-properties can have an array of phandles as
well.

It says we can have maximum one item in "required-opps" in "opp" node
and you are right that we could have here more. I'll fix it.

OK, this patch can be actually dropped. The dtschema will bring
constraints of 1-8 number of items here, which should cover all cases
for both opps - v2 and v2-kryo-cpu.
