I guess you have and old dts where clock/clock-names are in the sound
node.  Instead the clock/clock-names properties should be specified
in the CODEC's node, the related binding's documentation can be found
in Documentation/devicetree/bindings/mfd/arizona.txt. Also please see
patch 3/4, there is no clock properties in the sound card's DT binding.
