[ARM] S3C24XX: Remove hardware specific registers from DMA
calls
The S3C24XX DMA API channel configuration registers are being passed
values comprised of register values which makes it hard to move the
API to cover both the S3C24XX and S3C64XX.
These values can be calculated from knowing which device the channel
is connected to, so remove them from the two calls s3c2410_dma_config
and s3c2410_dma_devconfig.
