[PATCH AUTOSEL 4.9 1/7] ALSA: hda/realtek: Fix pop noise on ALC225

[Sasha Levin]

From: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx>

[ Upstream commit 3b36b13d5e69d6f51ff1c55d1b404a74646c9757 ]

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.
