[U-Boot] [PATCH 1/3] arm:mmc:goni/exynos: Fix wrong mmc base register devices offset.

[Przemyslaw Marczak <p.marczak@samsung.com>]

Hi Minkyu,

 > On s5pc1xx mmc devices offset is multiply of 0x100000,
> wrong value was 0x10000. Register offset always points
> to mmc 0 before this change.
>
> Add macro definition of mmc dev register offset to s5pc1xx and
> exynos mmc.

Could you review this patch, please?
