    tegra124: use known-good drive for fast-train only
    
    A higher drive setting is used for fast link training, once the
    link training succeeds, a known-good drive setting will be used
    for the main stream transactions.
    For full link training sequence, the sink devices may ask for a
    preferred drive setting, thus this drive setting should be used
    for the main stream transactions too.
    
    BUG=chrome-os-partner:32129
    TEST=all panels on blaze/big devices work fine.
