ALSA: hda/realtek - Fix S3 pop noise on Dell Wyse

[ Upstream commit 52e4e36807aeac1cdd07b14e509c8a64101e1a09 ]

Commit 317d9313925c ("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.
