mmc: remove s3cmci driver
The s3c24xx platform is gone, so this driver can be removed as well. Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Acked-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

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.
