dmaengine: Add flags parameter to dmaengine_prep_dma_cyclic()
With this parameter added to dmaengine_prep_dma_cyclic() the API will be in sync with other dmaengine_prep_*() functions. The dmaengine_prep_dma_cyclic() function primarily used by audio for cyclic transfer required by ALSA, we use the from audio to ask dma drivers to suppress interrupts (if DMA_PREP_INTERRUPT is cleared) when it is supported on the platform.
