dev-amdgpu: Add GART translations to GPUFS checkpoint

Earlier, the GART entries were not being checkpointed. Therefore, during
checkpoint restore, certain SDMA instances were initialized with
incorrect addresses that led to incorrect behavior. This commit
checkpoints the GART entries and restores them.
