As this controller is embedded on different SoC families, provide: * a family-specific "r-car-gen3" compatible and a more specific "r8a77951" one * a family-specific "rzn1" compatible and a more specific "r9a06g032" one More compatibles can be added later if new SoCs with this controller must be supported.
