Lu, Han 0a67352153 ALSA: hda - reset display codec when power on
In SKL, HDMI/DP codec and PCH HD Audio Controller are in different power wells,
so it's necessary to reset display audio codecs when power well on, otherwise
display audio codecs will disappear when resume from low power state.
Reset steps when power on:
    enable codec wakeup -> azx_init_chip() -> disable codec wakeup

The callback for codec wakeup enable/disable is in drivers/gpu/drm/i915/.
