The rockchip,dwc3.yaml schema defines a single DWC3 node, but the RK3399 uses the discouraged parent wrapper node and child 'generic' DWC3 node. The intent was to modify the RK3399 DTs to use a single node, but the DT changes were rejected for ABI reasons. However, the schema was accepted as-is. To fix this, we need to move the RK3399 binding to its own schema file. The RK3328 and RK3568 bindings are correct and use a single node.
