mmc: remove s3cmci driver 

The s3c24xx platform is gone, so this driver can be removed as well.

This selects a driver for the MCI interface found in
Samsung's S3C2410, S3C2412, S3C2440, S3C2442 CPUs.
If you have a board based on one of those and a MMC/SD
slot, say Y or M here.

Enable the hardware support for SDIO interrupts instead of using
the generic polling code.

config MMC_S3C_PIO
bool "Use PIO transfers only"
help
Use PIO to transfer data between memory and the hardware.
PIO is slower than DMA as it requires CPU instructions to
move the data. This has been the traditional default for
the S3C MCI driver.
config MMC_S3C_DMA
bool "Use DMA transfers only"
help
Use DMA to transfer data between memory and the hardware.
Currently, the DMA support in this driver seems to not be
working properly and needs to be debugged before this
option is useful.
