Not aligned.
Please fix it.

How about union the setup-sdhci-gpio.c to setup-sdhci file?
I think don't need to separate setup-sdhci and setup-sdhci-gpio file.

The S5PC100_PA_HSMMC0/1/2 definitions are used only here.
It seems better to define S3C_PA_HSMMC0/1/2 using directly
S5PC100_PA_HSMMC(x) instead of S5PC100_PA_HSMMC0/1/2.
