ALSA: hda/via - Disable broken dynamic power control
Since the transition to the generic parser, the actual routes used there don't match always with the assumed static paths in some set_widgets_power_state callbacks. This results in the wrong power setup in the end. As a temporary workaround, we need to disable the calls together with the non-functional dynamic power control enum.
