ata/pata_arasan_cf: fill dma chan->private from pdata->dma_priv
Some DMA controllers (eg: drivers/dma/dw_dmac*) allow platform specific configuration for dma transfers. User drivers need to set chan->private field of channel with pointer to configuration data. This patch takes dma_priv data from platform data and passes it to chan->private_data, in order to pass platform specific configuration to DMAC controller.
