[U-Boot] [PATCH] fsl-ddr: Fix power-down and ODT timing settings

[Liu Dave-R63238]

> 3. TIMING_CFG_5[RODT_ON] should be set to WL-2
> 4. TIMING_CFG_5[RODT_OFF] should be set to WL-1
> 5. TIMING_CFG_5[WODT_ON] should be set to WL-2
> 6. TIMING_CFG_5[WODT_OFF] should be set to WL-1

I would like hold on the patch, There are still issue on ODT
settings.
Please don't apply the patch. I will provide one new patch
to replace it.

Thanks, Dave
