dmaengine: tegra210-adma: add pause/resume support During an audio playback session it is observed that, audio goes off after few seconds of continuous pause and play. No audio is heard even when the playback is resumed. The reason for above is, currently ADMA driver does not handle DMA_PAUSE/ DMA_RESUME and relevant callbacks for dma_device are not implemented. This patch implements device_pause and device_resume callbacks for the device. During pause TRANSFER_PAUSE bit of dma channel control register is set and the same is cleared during resume.
