commit 3b36b13d5e69d6f51ff1c55d1b404a74646c9757 upstream.

Commit 317d9313925c ("ALSA: hda/realtek - Set default power save node to
0") makes the ALC225 have pop noise on S3 resume and cold boot.

So partially revert this commit for ALC225 to fix the regression.

Fixes: 317d9313925c ("ALSA: hda/realtek - Set default power save node to 0")
