drm/tegra: Support NVIDIA downstream
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.
