iommu/tegra: gart: Provide default ->map_sg() callback
Commit 315786ebbf4a ("iommu: Add iommu_map_sg() function") adds a new
->map_sg() callback and provides a default implementation that drivers
can use until they implement a hardware-specific variant. Unfortunately
the Tegra GART driver was not updated as part of that commit, so that
iommu_map_sg() calls on a domain provided by the GART cause an oops.
Fixes: 315786ebbf4a ("iommu: Add iommu_map_sg() function")
