ucm2: Intel: avs: Add UCM for renamed AVS HD-Audio, DMIC and HDMI

[GitHub pull_request - opened <github@alsa-project.org>]

alsa-project/alsa-ucm-conf pull request #871 was opened from archerallstars:

Add UCM for the renamed Intel AVS cards so PipeWire ACP can load HiFi on Kaby Lake machines that no longer use the old `hdaudioB0D2` / DMI long names.

## Hardware (live-tested)

| | |
| --- | --- |
| Machine | Acer Swift SF514-52T (DMI `Carlsberg_KL`) |
| CPU | Intel Core i5-8250U (Kaby Lake-U) |
| PCI audio | `8086:9d71` subsystem `1025:1225` |
| Codec | Realtek ALC255 (`0x10ec0255` / `0x10251225`) |
| HDMI codec | Intel Kabylake HDMI (`0x8086280b`) |
| Driver | `snd_soc_avs` (default `dsp_driver=0`) |
| Kernel | `7.2.9-200.fc44.x86_64` (Fedora Silverblue 44) |

```
 0 [DMIC    ]: avs_dmic    - AVS DMIC
 1 [PROBE   ]: avs_probe_mb - AVS PROBE
 2 [HDAudio ]: avs_hdaudio - AVS HD-Audio
 3 [HDMI    ]: avs_hdaudio - AVS HDMI
```

Playback: `hw:HDAudio,0` (analog), `hw:HDMI,0/1/2` (HDMI1/2/3).  
Capture: `hw:DMIC,0` (internal array), `hw:HDAudio,0` (analog headset).

## What this adds

Lookups:

- `ucm2/conf.d/avs_hdaudio/AVS HD-Audio.conf`
- `ucm2/conf.d/avs_hdaudio/AVS HDMI.conf`
- `ucm2/conf.d/avs_dmic/AVS DMIC.conf`

Profiles:

- **AVS HD-Audio** — `HDA/HiFi-analog.conf` for Speaker / Headphones. Extra `Headset` device on `pcm0c` when `Front Headphone Jack` exists. Analog capture has no `Capture Switch` on this BIOS (mic pins left N/A); topology still exposes `HDAudio Analog`. Format is 24-bit left-justified in `S32_LE`.
- **AVS DMIC** — PCM device 0 (after the card rename), `CaptureChannels 2`, `CaptureRate 48000`, `cset 'DMIC Volume' 100%` (the control boots at 0 / digital silence).
- **AVS HDMI** — three converters, `Number` 1/2/3 with `Device` 0/1/2. `codecs/hda/hdmi.conf` programs `IEC958 Playback Switch` at `index = Number - 1`, so `Number` is 1-based. `Number 0` yields index `-1`. Jack names on this SKU are `HDMI/DP Jack`, `HDMI/DP,pcm=1 Jack`, `HDMI/DP,pcm=2 Jack`.

Old `hdaudioB0D2` / `DMIC-2ch` / DMI long-name files are left in place.

## Proven on this chassis

| Path | Result |
| --- | --- |
| Internal speakers | playback works |
| 3.5 mm 2-ring headphones | playback works |
| 3.5 mm 3-ring CTIA headset mic | capture works on **Headset Microphone** |
| Internal AVS DMIC | capture works |
| HDMI / DisplayPort | playback works |

A 2-ring analog **microphone** on this combo jack is not compatible (pin `0x21` is OUT-only / `NO_HP_MIC`; the same plug is also silent on a Galaxy A25).

Analog headset **pins** still need a kernel quirk or userspace HDA hwdep verbs. AVS logs PCI SSID `1025:0000`, so `ALC255_FIXUP_ACER_HEADSET_MIC` never runs. This PR only binds the analog capture PCM and jack. The out-of-tree layer that programs CTIA (`0x45=0xd489`) and pin `0x19` IN+VREF_80 lives in https://github.com/archerallstars/acer-swift-sf514-52t (`scripts-audio-fix`). WirePlumber capture `Mult` boosts are also out of scope here.

## Relation to #571

[#571](https://github.com/alsa-project/alsa-ucm-conf/pull/571) is the generic Intel AVS renamed-card set (including I2S codecs). This PR is the HD-Audio + DMIC + HDMI subset that is live on ALC255, with three deltas from that branch:

1. HDMI `Number` is 1-based (`1/2/3` with `Device` `0/1/2`). #571 uses `Number 0` for PCM 0.
2. DMIC sets `CaptureChannels 2`. ACP assumes stereo when the count is omitted and fails with `EINVAL` on a 4-channel array ([comment on #571](https://github.com/alsa-project/alsa-ucm-conf/pull/571#issuecomment-5608938568)). This NHLT is stereo.
3. Headset analog capture device, because `HiFi-mic.conf` is skipped without `Capture Switch`.

This PR does not add the I2S codec UCMs from #571.

The kernel still exposes three cards. PipeWire ACP profiles each card. A combined/linked UCM (one logical onboard device) is the open design point on #571; these files match the split that works with current ACP on this laptop.
