Add a new IO virtual memory allocation API to allow clients to allocate non-GEM memory in the Tegra DRM IOMMU domain. This is required e.g. for loading client firmware when clients are attached to the IOMMU domain. The allocator allocates contiguous physical pages that are then mapped contiguously to the IOMMU domain using the iova_domain library provided by the kernel. Contiguous physical pages are used so that the same allocator works also when IOMMU support is disabled and therefore devices access physical memory directly.
