When I test it, I can get the clock pointer by devm_clk_get() as following:

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.
