Doesn't need required-opp binding in the opp nodes as they are only used for genpd based devices. - cpr-based that require power-domain in the cpu nodes and use various source to decide the correct voltage and freq Require required-opp binding since they need to be linked to the related opp-level. When the schema was introduced, it was wrongly set to always require these binding but this is not the case for pre-cpr devices. Make the power-domain and the required-opp optional and set them required only for qcs404 based devices.
