mmc: sdhci-s3c: remove platform dependencies
plat/regs-sdhci.h is not used anywhere but in the sdhci-s3c driver, so it can become a local file there and all other inclusions removed. plat/sdhci.h is used only to define the platform devices, and with the exception of the platform_data structure not needed by the driver, so we can split out the platform_data definition instead and leave the rest to platform code.
