ASoC: amd: yc: Support mic on another Lenovo ThinkPad E16 Gen 2 model

The internal microphone on the Lenovo ThinkPad E16 model requires a
quirk entry to work properly. This was fixed in a previous patch (linked
below), but depending on the specific variant of the model, the product
name may be "21M5" or "21M6".

The following patch fixed this issue for the 21M5 variant:

This patch adds support for the microphone on the 21M6 variant.
