[PATCH] ALSA: hda/intel: Add quirk for TongFang devices with pop noise

[Werner Sembach]

When audio stops playing and sometimes when it starts playing, there is an
audible "pop" noise when using headphones on most Tongfang GMxMxxx,
GKxNxxx, GMxZxxx, GMxTxxx, and GMxAxxx devices.

Disabling power saving for the Realtek codec fixes this noise. Presumably
it is triggered on some power event in the audio circuit.
