sound_card_init: add Max98373 boot time calibration logic

1. Implement functions to access the DSM calibration data from DSP.
2. Implement max98373 boot time calibration flow as the following
   steps:
   a. Limit the speaker volume to protect the speakers.
   b. Check whether the speakers are overheated.
   c. Trigger the DSM calibration from DSP.
   d. Decide and apply a good calibration value and remove the speaker
      output limitation.
