According to Documentation/devicetree/bindings/soc/fsl/guts.txt we have
the following compatibles:
"fsl,qoriq-device-config-1.0"
"fsl,qoriq-device-config-2.0"
"fsl,<chip>-device-config"
"fsl,<chip>-guts"
"fsl,qoriq-device-config" is none of them and I don't think you should
give this SoC specific thing a generic compatible.
"fsl,ls1046a-device-config" would be better.
