Reset charger configure and constraint for glink down

Browse source 
Reset charger configure and constraint for glink down, so that
AP will resend the charger configure and constraint to ADSP
battery management, otherwise uninitilized value of charger
configure and constraint will be used in ADSP side after ADSP
restart, and then power max value will use default value 0;
