dmaengine: ti: omap-dma: Improved memcpy polling support
When a DMA client driver does not set the DMA_PREP_INTERRUPT because it does not want to use interrupts for DMA completion or because it can not rely on DMA interrupts due to executing the memcpy when interrupts are disabled it will poll the status of the transfer. If the interrupts are enabled then the cookie will be set completed in the interrupt handler so only check in HW completion when the polling is really needed.
