[PATCH v1 5/8] arm64: dts: qcom: hawi-mtp: enable audio playback and capture

[Prasad Kumpatla <prasad.kumpatla@oss.qualcomm.com>]

Wire up the audio use cases on the Hawi MTP board on top of the LPASS
nodes added to the SoC dtsi.

Add the sound card (qcom,hawi-sndcard) with the TDM playback, WCD
playback/capture and VA DMIC capture DAI links and the associated audio
routing. Describe the WCD9395 codec, enable the RX and TX SoundWire
controllers with their WCD RX/TX satellite ports, and add the WSA8855
speaker amplifier on i2c3. Configure the VA macro DMIC supply and the
required TLMM pin states (WCD reset, WSA IRQ, WSA shutdown).
