Shashank Singh 701c0efa8d gpu: nvgpu: enable syncpoint shim when nvlink is disabled ...

Create an iova for syncpoint shim region in case iommu is enabled and
nvlink is disabled. This iova is then used to created nvgpu mem with
nvgpu_mem_create_from_phys. Which is then used to create gpu mappings.
Instead of creating another variable g->syncpt_mem's priv is used to
store the sgt which needs to be freed on deinit.
