Subject: [PATCH 2/8] arm64: dts: qcom: msm8939: Disable lpass_codec by
 default

Update for recent changes to msm8916.dtsi in commit a5cf21b14666
("arm64: dts: qcom: msm8916: Disable audio codecs by default") and
make lpass_codec disabled by default for devices that are not using
the audio codec functionality inside MSM8939.
