[PATCH v2 1/5] dt-bindings: display/msm: dpu-msm8998: add missing DPU opp-table

[Krzysztof Kozlowski]

The 'display-controller' child (DPU) of Display SubSystem (MDSS) uses
opp-table, so reference it which allows restricting DPU schema to fixed
list of properties.

Fixes: 6e986a8f1cf1 ("dt-bindings: display: msm: Add binding for msm8998 dpu")
