This serie aim to add the following audio support for the Genio 350-evk:
- Playback
  - 2ch Headset Jack (Earphone)
  - 1ch Line-out Jack (Speaker)
  - 8ch HDMI Tx
- Capture
  - 1ch DMIC (On-board Digital Microphone)
  - 1ch AMIC (On-board Analogic Microphone)
  - 1ch Headset Jack (External Analogic Microphone)

Of course, HDMI playback need the MT8365 display patches [1] and a DTS
change documented in "mediatek,mt8365-mt6357.yaml".

Rebase on top of sound/for-next branch and the
Angelo's serie "SoC: Cleanup MediaTek soundcard machine drivers" [2]
Work branch with all patches [5]

Applied patch:
- mfd: mt6397-core: register mt6357 sound codec

Test passed:
- mixer-test log: [3]
- pcm-test log: [4]

  - micbias property: use microvolt value instead of index.
  - mediatek,i2s-shared-clock property removed.
  - mediatek,dmic-iir-on property removed.
  - mediatek,dmic-irr-mode property removed.
  - Change dmic-two-wire-mode => dmic-mode to be aligned with another SoC
  - Remove the spurious 2nd reg of the afe.
- Manage IIR filter feature using audio controls.
- Fix audio controls to pass mixer-test and pcm-test.
- Refactor some const name according to feedbacks.
- Rework the codec to remove spurious driver data.
- Use the new common MTK probe functions for AFE PCM and sound card.
