msm: kgsl: Switch pagetables in stream for IOMMU

Switch IOMMU pagetables by using GPU commands instead of using the CPU.
This is better for performance because the synchronization required for
switching pagetables instream using GPU commands is less expensive
comparedto synchronization required when switching pagetables using the
CPU
