drm/nouveau/platform: probe IOMMU if present Tegra SoCs have an IOMMU that can be used to present non-contiguous physical memory as contiguous to the GPU and maximize the use of large pages in the GPU MMU, leading to performance gains. This patch adds support for probing such a IOMMU if present and make its properties available in the nouveau_platform_gpu structure so subsystems can take advantage of it.
