Add support for NVIDIA Tegra general purpose DMA driver for Tegra186 and Tegra194 platform.
v16 -> v17: * Updates in terminate_all() and pause(). * Moved DMA busy check to configure_next_sg() from issue_pending() * shortened variable names - bytes_requested -> bytes_req; bytes_transferred -> bytes_xfer * Correction in burst_size calculation
