power: fg-alg: add min_start_soc to begin the capacity learning 



Currently, capacity learning begins based on SOC threshold and
battery temperature. Since the SOC threshold to begin cannot be
qualified in certain low battery conditions, add another minimum
SOC threshold for a better qualification.
