BugLink: https://bugs.launchpad.net/bugs/1878554

The reverted patch was introduced by stable-patches, and this SRU
plans to revert the patch, the commit id is from oem-5.6 kernel,
so maybe in the Groovy and unstable kernel, the commit id is not
same as this one.

[Impact]
On Lenovo P520 with Nvida P4000 grahic card, the hdmi audio doesn't
work.

[Fix]
revert an existing patch to let patch_nvhdmi support component.

[Test Case]
boot the system, plug the hdmi/dp monitor, the hdmi audio could work,
wait for 10 mins until the screen become black, wake up the screen and
check the audio, still work well.

[Regression Risk]
Low, after reverting the patch, it is aligned to mainline kernel
