Add DT binding of max98390 amplifier driver.

Signed-off-by: Steve Lee steves.lee@maximintegrated.com ---

Changed since V6: * Re-confirm yaml dt binding check * Add minimum and maximum value for each temperature_calib and r0_calib * Add maxim prefix for naming. Changed since V5: * Change txt to yaml and fix up the examples. Changed since V4: * No changes. Changed since V3: * No changes. Changed since V2: * No changes. Changed since V1: * Modified sample text in example
