[PATCH 1/3] ASoC: amd: acp: add DMI override for ACP70 flag

[hasunpark]

From: Hasun Park <hasunpark@xxxxxxxxx>

Some ASUS ProArt PX13 systems expose ACP ACPI config flags that can
select a non-working fallback path.

Add a DMI override in snd_amd_acp_find_config() for ACP70+ boards and
return 0 so ACP ACPI flag-based selection is skipped on this platform.

This keeps machine driver selection on the intended SoundWire path.
