mmc: sdhci-s3c: use the sdhci-pltfm.c and move the header file

This patchset is the purpose for using sdhci-pltfm.c and
removing the arch dependency.
The sdhci-s3c has too heavy arch dependency.
For example, if work for sdhci-s3c.c at mmc-tree, sometime need to change sdhci.h for Samsung-Soc. But now we need to work at both mmc-next tree and Samsung-SoC tree.
I think this is very inefficient and can conflict to merge.
So remained at least dependency and moved the header file to mmc folder.

And sdhci-s3c changed to use the sdhci-pltfm.c.
There is no reason that didn't use the sdhci-pltfm.c.
If we use the sdhci-pltfm.c,we can easily maintain the common part.

In future, i will work more removing the arch dependency.

This patchset based on mmc-next tree.

Changlog V2:
- modified driver/mmc/host/Kconfig
- Add the comments for s3c64xx
- based-on latest mmc-tree.

Hi Chris.

I want to reduce the least arch dependency.
Now, we are working the twice for sdhci-s3c.c.(Samsung-SoC tree and mmc-tree) It's very inefficiency.
There is no reason that the generic platdata & regs-sdhci.h can't move into mmc driver. (In other device driver's case, have maintained in mmc-driver)
If will move into mmc-driver, we can maintain the efficient more than before. I want to know your opinion.

Best Regards,
Jaehoon Chung
