[PATCH 3/3] arm64: dts: qcom: monaco-arduino-monza: Add overlay for Waveshare WM8960 Audio HAT

[Srinivas Kandagatla]

Add a DT overlay for the Waveshare WM8960 Audio HAT connected to the
40-pin JHAT connector. The overlay adds the WM8960 fixed MCLK clock,
the WM8960 codec on I2C0, and the corresponding I2S1 playback and
capture DAI links to the sound card.
