ARM: S3C64XX: DMA: Debugged alloc's with GFP_KERNEL flag in Intr context.

s3c2410_dma_enqueue makes call to kzalloc and dma_pool_alloc with GFP_KERNEL
flag set, this can be an issue for drivers, like I2S, which call
s3c2410_dma_enqueue from dma-bufferdone callback.

Change the flag GFP_KERNEL to GFP_ATOMIC to avoid any problems.
