dmaengine: Fix a bug about BUG_ON() on DMA engine capability DMA_INTERRUPT.
The device->device_prep_dma_interrupt function is used by DMA_INTERRUPT capability, not DMA_ZERO_SUM. Signed-off-by: Zhang Wei <wei.zhang@freescale.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
