[PATCH v6 3/3] arm64: dts: qcom: sm8450-hdk: add sound support

[Krzysztof Kozlowski]

From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>

Add sound support to SM8450 HDK board.  Tested setup so far is only two
speakers (working) and head-phones (only one channel working).

Changes since v5:
1. Use TX_CODEC_DMA_TX_3 for VA capture.
2. Reverse order of speakers (left/right).
3. Drop duplicated wcd-playback-dai-link and add wcd-capture-dai-link.

Changes since v3:
1. None.

Changes since v2:
1. Use ACTIVE_LOW for qcom,wcd9380-codec reset-gpios.

Changes since v1:
1. Sort.
2. Correct include - do not use deprecated one and drop q6asm.h (not
   used).
