k3_avs driver checks opp_ids when probing and overwrites the voltage values in vd_data for the respective board. The new k3_avs_check_opp() can be called from board files to check the efuse data and returns 0 if valid.
Also add the same check in k3_avs_program_voltage() to error out if the efuse data was not valid.
