dmaengine: s3c24xx: remove unused ‘cdata’

Browse Source 
In s3c24xx_dma_get_phy(), variable ‘cdata’ is initialized but never used, which
leads to warning with W=1. Removing this make pdata unused.

drivers/dma/s3c24xx-dma.c: In function ‘s3c24xx_dma_get_phy’:
drivers/dma/s3c24xx-dma.c:293:30: warning: variable ‘cdata’ set but not used [-Wunused-but-set-variable]
  struct s3c24xx_dma_channel *cdata;

So remove both of them.
