    nb/amd/mct_ddr3: Set read DQS delay to 1UI before calculating read latency
    
    The AMD Family 15h BKDG rev. 3.14 indicates that the maximum read latency
    must be calculated prior to DQS position training, however the read
    latency calculations use read DQS delay values that have not been
    set prior to DQS position training.
    
    Set the read DQS delay values to 1UI (i.e worst case) before calculating
    the read latency prior to DQS position training.
