Subject: [PATCH v5 4/9] ASoC: dt-bindings: wcd938x-sdw: add bindings for wcd938x-sdw

Qualcomm WCD9380/WCD9385 Codec is a standalone Hi-Fi audio codec IC
connected over SoundWire. This device has two SoundWire devices RX and
TX respectively. This bindings is for those slave devices on WCD9380/WCD9385.
