This patch modifies TegraDRM to compile on NVIDIA downstream kernel. Currently buffers are pinned to virtual drm device. In upstream this is ok since the buffers will be remapped into the TegraDRM maintained IOMMU domain. However, NVIDIA downstream kernel relies on DMA mapping API and hence requires that the buffers are pinned to the real hardware device. In addition, this patch modifies code to use downstream power-management APIs if the downstream option is enabled.
