Subject: ALSA: hda/realtek - Fix Dell AIO LineOut issue

From: Kailang Yang <kailang@realtek.com>

commit 9226665159f0367ad08bc7d5dd194aeadb90316f upstream.

Dell AIO had LineOut jack.
Add LineOut verb into this patch.

[ Additional notes:
  the ALC274 codec seems requiring the fixed pin / DAC connections for
  HP / line-out pins for enabling EQ for speakers; i.e. the HP / LO
  pins expect to be connected with NID 0x03 while keeping the speaker
  with NID 0x02.  However, by adding a new line-out pin, the
  auto-parser assigns the NID 0x02 for HP/LO pins as primary outputs.
  As an easy workaround, we provide the preferred_pairs[] to map
  forcibly for these pins. -- tiwai ]
