Subject: [PATCH 1/3] arm64: dts: qcom: sc7280: Add nodes for va tx and rx macros and external codecs

SC7280 has VA, TX and RX macros with SoundWire Controllers to attach with
codecs like WCD938x, max98360a using soundwire masters and i2s bus.
Add these nodes for sc7280 based platforms audio use case.
