ALSA: hda/realtek: Fix pop noise on ALC225

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.
