ASoC: wm_adsp: Expose the DSP power down actions as wm_adsp_power_down()

Browse Source 
To support self-booting DSPs that operate outside of a conventional DAPM
event life cycle expose a companion function to wm_adsp_power_up() so
that the correct state of the DSP firmware and controls can be recorded.
