ASoC: amd: acp: Add DMI quirk for ASUS Zenbook S16 UM5606GA

Browse Source 
The ASUS Zenbook S16 (UM5606GA) with AMD Ryzen AI 9 465 (Strix Point,
ACP 7.0) has a BIOS that incorrectly sets the ACPI property
'acp-audio-config-flag' to 0x10 (FLAG_AMD_LEGACY_ONLY_DMIC) for the ACP
device. This prevents snd_pci_ps from probing the SoundWire bus, resulting
in no internal audio (dummy output only).

The hardware uses a Cirrus Logic CS42L43 (headphone/jack) and four CS35L56
smart amplifiers (speakers), all on SoundWire link 1. The corresponding
machine table entry (acp70_cs42l43_l1u0_cs35l56x4_l1u0123) already exists
in amd-acp70-acpi-match.c and correctly describes this topology.

Add a DMI quirk to override the flag to 0, consistent with the existing
entry for the HN7306EA.
