dmaengine: tegra-adma: Add support for Tegra210 ADMA
Add support for the Tegra210 Audio DMA controller that is used for transferring data between system memory and the Audio sub-system. The driver only supports cyclic transfers because this is being solely used for audio. This driver is based upon the work by Dara Ramesh <dramesh@nvidia.com>.
