Subject: [PATCH v5 3/7] dt-bindings: display: renesas,du: Add missing
 constraints

From: Tomi Valkeinen <tomi.valkeinen+renesas@...asonboard.com>

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.
