ASoC: qcom: lpass-cpu: Use optional clk APIs

This driver spits out a warning for me at boot:

 sc7180-lpass-cpu 62f00000.lpass: asoc_qcom_lpass_cpu_platform_probe() error getting optional null: -2

but it looks like it is all an optional clk. Use the optional clk APIs
here so that we don't see this message and everything else is the same.
