ARM: S3C24XX: don't use uninitialized variable in dma.c 

Commit 8970ef47 (S3C24XX: Remove hardware specific registers from DMA
calls) removed the parameter dcon in s3c2410_dma_config() and calculates
it on its own. So the debug-output for the old parameter can go, too.
Fixes:

arch/arm/plat-s3c24xx/dma.c: In function 's3c2410_dma_config':
arch/arm/plat-s3c24xx/dma.c:1030:2: warning: 'dcon' is used uninitialized in this function
