[PATCH] ALSA: hda/conexant: Set mic pin VREF to 0x24 on headset mic plug

[songxiebing]

From: Bob Song <songxiebing@xxxxxxxxxx>

For 3-pole headset microphones, the mic pin VREF must always be
configured to 0x24 regardless of the headset type, otherwise the
mic will not be able to record audio. Move the setting of the mic
pin widget control to a common path.
