If applied my patches, then i want to apply this at first, not "s5p_sdhci: support the Driver model for Exynos".
But I want to know Simon's opinion about this patch. I don't know correct why passed the buswidth.

The below patch will resend with other patch..(Modify Device-tree and remove the unused codes.)
