The binding is missing maxItems for all renesas,cmms and renesas,vsps
properties. As the amount of cmms or vsps is always a fixed amount, set
the maxItems to match the minItems.

Also add the minItems and maxItems to the top level properties.

AFAIK these two additions are not needed, as they already match the
values defined at the top level.

The rest LGTM.

But if we add a new SoC, which has 5 vsps, we would need to increase the 
values in the top level. Which would then mean these are needed, and I'm 
sure adding them could be missed.

Let's keep things consistent with maxItems specified everywhere (my
preference is to not specify the items count at the top level hereas I
don't see any value in doing so, but I won't fight on that one if it's
what it takes to get the bindings merged).
