Subject: [PATCH] ALSA: hda - Fix onboard audio on Intel H97/Z97 chipsets

The recent Intel H97/Z97 chipsets need the similar setups like other
Intel chipsets for snooping, etc.  Especially without snooping, the
audio playback stutters or gets corrupted.  This fix patch just adds
the corresponding PCI ID entry with the proper flags.
