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.
BRANCH=none
