[PATCH] ASoC: amd: yc: Add Lenovo ThinkPad E16 Gen 2 (21JN) to quirks

Hi,

I have a Lenovo ThinkPad E16 Gen 2 (AMD Ryzen 7 7735HS) with machine type "21JN".
Currently, the internal digital microphone (DMIC) is not detected on Debian 13 (kernel 6.18).

Similar to the "21M5" model, this "21JN" model also requires a DMI quirk entry to enable the internal microphone.

Could you please add the "21JN" model to the quirk list in `sound/soc/amd/yc/acp6x-mach.c`?

DMI info:
- Vendor: LENOVO
- Product Name: 21JN

Thank you,

Seiji Adachi
