ALSA: hda - Force polling mode on CNL for fixing codec communication 



[ Upstream commit fa763f1b2858752e6150ffff46886a1b7faffc82 ]

We observed the same issue as reported by commit a8d7bde2
("ALSA: hda - Force polling mode on CFL for fixing codec communication")
We don't have a better solution. So apply the same workaround to CNL.
