[PATCH 1/2] ASoC: amd: acp-config: force SoundWire probe on HP OmniBook X Flip 14

[Ville Saarinen]

The BIOS on the HP OmniBook X Flip 14-kc0xxx (board 8EA1, Strix Point,
ACP 7.2) reports acp-audio-config-flag = FLAG_AMD_LEGACY_ONLY_DMIC. That
binds the legacy ACP driver and registers a PDM-only card, so the
SoundWire links are never scanned: the two TAS2783 speaker amplifiers on
link 0 and the RT712-VB jack codec on link 1 do not enumerate and the
machine ends up with no usable playback path at all.

Add a DMI entry for the board so the flag is overridden to 0 and
snd_pci_ps probes instead.

Developed with AI assistance. The assistant read the board's ACP
configuration flag out of the running system, identified the flag
override as the fix and drafted the DMI entry.

All hardware measurements quoted above were run by the submitter on the
affected machine. The submitter has reviewed the change, understands it
and takes responsibility for it.
