Subject: [PATCH v2 2/2] dt-bindings: display: renesas,du: add top-level constraints

Properties with variable number of items per each device are expected to
have widest constraints in top-level "properties:" block and further
customized (narrowed) in "if:then:".  Add missing top-level constraints
for clocks, clock-names, interrupts, resets, reset-names, renesas,cmms
and renesas,vsps.
