    rockchip/rk3399: fix sdram training issue
    
    After write leveling for all ranks, check the
    PHY_CLK_WRDQS_SLAVE_DELAY result, if the two ranks in one slice both
    meet (0x200-PHY_CLK_WRDQS_SLAVE_DELAY < 0x20) or
    (0x200-PHY_CLK_WRDQS_SLAVE > 0x1E0), enable PHY_WRLVL_EARLY_FORCE_ZERO
    for this slice, and trigger write leveling again.
