ALSA: hda/realtek: Add new alc2xx-fixup-headset-mic model

[ Upstream commit 50db91fccea0da5c669bc68e2429e8de303758d3 ]

Introduces the alc2xx-fixup-headset-mic model to simplify enabling
headset microphones on ALC2XX codecs.

Many recent configurations, as well as older systems that lacked this
fix for a long time, leave headset microphones inactive by default.
This addition provides a flexible workaround using the existing
ALC2XX_FIXUP_HEADSET_MIC quirk.
