dmaengine: Pass flags via device_prep_dma_cyclic() callback
Change the parameter list of device_prep_dma_cyclic() so the DMA drivers can receive the flags coming from clients. This feature can be used during audio operation to disable all audio related interrupts when the DMA_PREP_INTERRUPT is cleared from the flags.
