This is preparatory work for further SMMUv3.3 features including RME-DA.
We are adding in patches originally authored by Pierrick Bouvier 
<pierrick.bouvier@linaro.org> and Gustavo Romero <gustavo.romero@linaro.org>
in a way that will avoid conflicts with Tao Tang's upcoming SMMUv3 Secure
state patches. Since Root registers do not use the banking system, this
should only conflict around the offset check near smmu_write_mmio and
smmu_read_mmio.
