If card and host are supported DDR mode, then it can be used the DDR mode.
This patch-set has dependency about beomho's patch-set.
(Based-on u-boot-samsung repository)

It's result for loading image.

sdhci controller ->5260488 bytes read in 259 ms (19.4 MiB/s)
dwmmc controller without DDR mode -> 5260488 bytes read in 202 ms (24.8 MiB/s)
dwmmc controller with DDR mode -> 5260488 bytes read in 118 ms (42.5 MiB/s)

Download the 400M image with lthor.
sdhci controller -> 59.4sec (Avg 6.95 MB/s)
