mmc: s3cmci: fix s3c2410_dma_config() arguments.
commit 7c48ed3383bfb2106694807361ec187fe8a4333d upstream.
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.
