[PATCH v2 0/2] ASoC: amd: acp: Support Huawei MateBook D 14 (NBM-WXX9)

[Samuel Leyva <samuelslg03idk@gmail.com>]

The Huawei MateBook D 14 AMD (NBM-WXX9) has the same ES8336 + ACP3x
audio layout as the already supported BOM-WXX9, but is missing from
the DMI tables, so only the DMIC-only driver binds and the speakers
do not work.

Patch 1 adds the DMI quirk.

Patch 2 greatly reduces a pop heard every time the speaker output powers
up (a faint one is still audible on this machine):
the speaker amplifier GPIO was driven from a SUPPLY widget, which DAPM
enables before the codec output. It is independent of patch 1.

Both were tested as an out-of-tree DKMS module on the NBM-WXX9.

Changes in v2:
- Patch 2: only move the speaker amplifier to the endpoint widget.
  The Headphone widget shares its power-up rank with the ES8316 output
  drivers, so the reordering did not hold for headphones (Sashiko).
- Patch 2: use braces on both if/else branches (Sashiko).
- Patch 2: add Fixes tag (Sashiko).
- Patch 1: unchanged.
