Dave Jiang cfe3dd8bd5 dmaengine: idxd: add missing callback function to support DMA_INTERRUPT

commit 2112b8f4fb upstream.

When setting DMA_INTERRUPT capability, a callback function
dma->device_prep_dma_interrupt() is needed to support this capability.
Without setting the callback, dma_async_device_register() will fail dma
capability check.
