ALSA: hda: codec: Reduce CONFIG_PM dependencies
CONFIG_PM is almost mandatory nowadays for real systems, but we have lots of CONFIG_PM dependent code in snd-hda-codec helper code. Let's reduce the dependencies of CONFIG_PM now. The only visible drawback would be a couple of superfluous trace entries for runtime PM, but we can live with that.
