gpu: nvgpu: Update __get_pte_size() to check IOMMU-ability
When generating the PTE size for a given mapping the code must
consider whether the GPU is being IOMMU'ed. The presence and
usage of an IOMMU implies the buffers will appear contiguous
to the GPU. Without an IOMMU we cannot assume that and therefor
must use small pages regardless of the size of the buffer to
be mapped.
