Subject: [PATCH 2/2] arm64: dts: fsl: ls1046a: Add the guts node in dts

For NXP ls1046a SoC, the i2c clock needs to be configured with the
appropriate bit of RCW, so we add the guts node (GUTS/DCFG global
utilities block) for the driver to read.

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.
