[ Upstream commit 38417f5fc8e3323218c19bd7e419eec4fb0697bd ]

Add DMI quirk to enable ACP6x sound card for HP Victus by HP Laptop
16-e1xxx, which fixes microphone not working issue.

Without this quirk, the DMIC on acp6x device is not properly enabled,
causing the microphone to not work.

LLM Generated explanations, may be completely bogus:

The background git searches finished and match the earlier analysis:

- **Mainline commit:** `38417f5fc8e33` — "Add DMI quirk for HP Victus
  Laptop 16-e1xxx"
- **Not in 6.18.y:** that commit is on `master` only
  (`stable/linux-6.18.y..master`)
- **Partial coverage in stable:** `205efd4619b86` already quirked board
  name `8A22` for Victus 16-e1xxx; the new patch adds a
  `DMI_PRODUCT_NAME` match for variants that don't hit existing entries

The backport recommendation stands: **YES** for Linux 6.18.44.
