mmc: s3cmci: fix s3c2410_dma_config() arguments.

The s3cmci driver is calling s3c2410_dma_config with incorrect data for the DCON register. The S3C2410_DCON_HWTRIG is implicit in the channel configuration and the device selection of S3C2410_DCON_CH0_SDI is incorrect as the DMA system may not select channel 0.
