The binding requires the node name to match a specific regex. The patch as
written does not validate:

arch/arm/boot/dts/sun8i-t3-cqa3t-bv3.dtb: opp_table0: $nodename:0: 'opp_table0'
does not match '^opp-table(-[a-z0-9]+)?$'
        From schema: Documentation/devicetree/bindings/opp/opp-v2.yaml

With the node renamed to "opp-table-cpu" (following H3), the devicetrees pass
validation. So with that one change:
