Commit 317d9313 ("ALSA: hda/realtek - Set default power save node to
0") makes the ALC225 have pop noise on S3 resume and cold boot.

The previous fix enable power save node universally for ALC225, however
it makes some ALC225 systems unable to produce any sound.

So let's only enable power save node for the affected Dell Wyse
platform.
