arm64: dts: qcom: msm8916: Fix lpass compat string to match yaml

The documented yaml compat string for the apq8016 is
"qcom,apq8016-lpass-cpu" not "qcom,lpass-cpu-apq8016". Looking at the other
lpass compat strings the general form is "qcom,socnum-lpass-cpu".

We need to fix both the driver and dts to match.
