This patch makes Samsung EXYNOS4 to use DMA PL330 driver
on DMADEVICE. The EXYNOS4 uses DMA generic APIs instead of
SAMSUNG specific S3C-PL330 APIs.

The client driver specifies the direction of the transfer
(DMA_TO_DEVICE or DMA_FROM_DEVICE) when requesting for a dma channel.
So, is the rqtype parameter required in the platform data for the dma
driver?

Thanks,
