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.
