    mtd: nand: timings: Fix tADL_min for ONFI 4.0 chips
    
    ONFI 4.0 spec defines different values for the tADL_min timing.
    Since we don't want to have different timings depending on the ONFI
    version, we just set tADL_min to the maximum value (the one specified
    in the ONFI 4.0 spec).
