sound fixes for 3.15-rc4

A few collections of small eggs that have been gathered during
the Easter holidays.  Mostly small ASoC fixes, with a HD-audio
quirk and a workaround for Nvidia controller.
ALSA: hda - Suppress CORBRP clear on Nvidia controller chips

The recent commit (ca460f86521) changed the CORB RP reset procedure to
follow the specification with a couple of sanity checks.
Unfortunately, Nvidia controller chips seem not following this way,
and spew the warning messages like:
  snd_hda_intel 0000:00:10.1: CORB reset timeout#1, CORBRP = 0

This patch adds the workaround for such chips.  It just skips the new
reset procedure for the known broken chips.
