[ Upstream commit 8fc8e903156f42c66245838441d03607e9067381 ]

The commit 0165c4e19f6e ("ALSA: hda: Fix hang during shutdown due to link reset") modified the shutdown callback of the HD-audio controller for working around a hang. Meanwhile, the actual culprit of the hang was identified to be the leftover active codecs that may interfere with the powered down controller somehow, but we took a minimal fix approach for 5.14, and that was the commit above.

Now, since the codec drivers go runtime-suspend at shutdown for 5.15, we can revert the change and make sure that the full runtime-suspend is performed at shutdown of HD-audio controller again. This patch essentially reverts the commit above to restore the behavior.
