Subject: [PATCH] ALSA: hda - Disable AA-loopback on ALC283 Chromebook

ALC283-based Chromebook suffers from occasional white noise, and it
turned out that this comes from AA-loopback.  Disable this output path
by just clearing mixer_nid, then the generic parser will skip the
creation of AA-loopback path.
