ALSA: hda/realtek: Fix pop noise on ALC225
BugLink: https://bugs.launchpad.net/bugs/1870604
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.

Title:
upgrading to 4.15.0-99-generic breaks the sound and the trackpad
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am using kubuntu LTS 18.04.
This morning I was promped to update the kernel to the 4.15.0-99-generic.
After the upgrade I did not manage to get any sound. I checked
everything, pavucontrol, alsamix, everything was in order, the streams
showed as if they were playing, however I couldn't get any sound from
the speakers headphones and I could not get any sound recorded either.
I then rebooted with the previous version of the Kernel, and have my sound
back without doing anything at all.
