[Trusty PATCH V2 3/3] ALSA: hda - Fix noisy outputs on Dell XPS13 (2015 model)

[Hui Wang]

From: Takashi Iwai <tiwai at suse.de>

BugLink: http://bugs.launchpad.net/bugs/1468582

The new Dell XPS13 also requires the similar quirk for fixing the
noisy outputs.  (But, as the codec was changed, now the fixup for
Latitude is used instead.)

(backport from commit 82d6d8a4034a7480d582791763c89c328c2a8f0c and
8b99aba70c5f581860736855e211cf981f438ad2)

[This patch merged part of commit 8b99aba7 into the commit 82d6d8a4.
The content of the commit 8b99aba7 is partly dropped, firstly I
dropped the part of adding QUIRK to two Latitude machines, since
these two machines already had MIC_PRESENCE QUIRK in the 3.13,
adding a new QUIRK will overwrite the old one; secondly I dropped
the part of changing power_save_node, since there is no this
feature in the 3.13 yet.]
