arm64: dts: qcom: msm8916-huawei-g7: Add sound card 



The huawei-g7 uses the msm8916-wcd-digital/analog audio codecs similar
to apq8016-sbc, so we can mostly copy paste it from there to make audio
work correctly. The main difference is the hphl-jack-type-normally-open
property, which is needed to avoid inverted audio jack detection.

Note that at least on my device the jack detection is not fully
reliable: sometimes headphones are detected as headsets (with
microphone). However, this is not a big problem for typical usage.
