alsa/hdmi: the sound is distorted when playing via nvidia hdmi

[Hui Wang]

[Impact]
When playing back the sound via nv hdmi, the sound is distorted, that is because
the osp1-b kernel backported the patch 9b6f7e7a296e17990aae298c809b001e99ddd151
ALSA: hda: program stripe bits for controller, but we didn't backport a follow-up
patch 053b055948e97268771de11f2ab9b2aa1640b68d ALSA: hda: program stripe control for codec

[Fix]
backport the missing patch 053b055948e97268771de11f2ab9b2aa1640b68d
ALSA: hda: program stripe control for codec

[Test Case]
set the machine to performance mode, boot up, plug the hdmi cable, and
choose nv hdmi as the output device, play sound, the sound is normal

[Regression Risk]
Low. It is specific to the codec with stripe capability (nv hdmi codec).

Same issue with Kernel 5.4.0-9 on Ubuntu 20.04 LTS.
No problem if i login with 5.3.0-24-generic

Please check if you install the nvidia graphic driver or not on the kernel of 5.4.0 and 5.3.0.
