ALSA: hda - fix headset mic problem for Dell machines with alc274

Confirmed with Kailang of Realtek, the pin 0x19 is for Headset Mic, and the pin 0x1a is for Headphone Mic, he suggested to apply ALC269_FIXUP_DELL1_MIC_NO_PRESENCE to fix this problem. And we verified applying this FIXUP can fix this problem.
