Peter Ujfalusi 2dde5b909e dmaengine: omap-dma: Add support to suppress interrupts in cyclic mode 
When requested (DMA_PREP_INTERRUPT is cleared in flags) disable all DMA
interrupts for the channel. In this mode user space does not expect
periodic reports from kernel about the progress of the audio stream.
PulseAudio for example support this type of mode.
