ASoC: qcom: audioreach: Add support for Speaker Protection module

Browse Source 
Speaker Protection is capability of ADSP to adjust the gain during
playback to different speakers and their temperature.  This allows good
playback without blowing the speakers up.

Implement parsing MODULE_ID_SPEAKER_PROTECTION from Audioreach topology
and sending it as command to the ADSP.
