Subject: [PATCH v3 0/4] dt-bindings: display: qcom,sm8[56]50-mdss: properly
 document the interconnect paths

The mdp1-mem is not supported on the SM8550 & SM8650 SoCs, so properly document
the mdp0-mem and cpu-cfg interconnect entries.

This fixes the following errors:
display-subsystem@...0000: interconnects: [[200, 3, 7, 32, 1, 7]] is too short
        from schema $id: http://devicetree.org/schemas/display/msm/qcom,sm8650-mdss.yaml#
display-subsystem@...0000: interconnect-names: ['mdp0-mem'] is too short
        from schema $id: http://devicetree.org/schemas/display/msm/qcom,sm8650-mdss.yaml#
