sound_card_init: add boot time calibration flow for max98390
The max98390 boot time calibration flow inlcudes the following steps:
1. Limits the speaker volume to protect the speakers.
2. Triggers the boot time calibration while playing some zeros to the
speakers.
3. Reads the result of calibration and decides whether to use it or not.
4. Applies a good calibration value and removes the speaker output
limitation.
