Subject: [PATCH] ASoC: amd: yc: Add support for Lenovo Yoga 7 16ARP8

From: meowmeowbeanz <meowmeowbeanz@....com>

Add DMI quirk entry for Lenovo Yoga 7 16ARP8 (83BS) to enable
digital microphone support via ACP driver.

Fixes microphone detection on this specific model which was
previously falling back to non-functional generic audio paths.
