[PATCH 1/2] ALSA: hda/realtek: Add quirk for HP Pavilion All-in-One 27-ca1xxx

[Zhang Heng]

This HP All-in-One desktop (model 27-ca1xxx) uses an ALC274 codec
and has no sound from either the internal speakers or the headphone
jack. The audio output requires a combination of a specific verb
setup and GPIO configuration to become functional. Additionally,
the power_save feature must be disabled; otherwise, audible clicks
or pops occur during power state transitions.
