[ARM] tegra: dma: Single buffered continuous DMA

- Added "single buffer continuous DMA" mode in addition to the
  "double buffer continuous DMA" mode that is already implemented
- Changed the queuing of next buffer to be more flexible for
  continuous DMA.  It can now get in-flight right after a transfer
  starts, or whenever the client enqueues a buffer.
