iommu/tegra-smmu: Changes for v4.3-rc1

A bunch of improvements by Russell King, along with a fix to restore
display support when using the SMMU. This was due to the SMMU driver
writing the wrong value of active TLB lines, effectively disabling the
TLB and causing massive underflows on the display controller because
of the latency introduced by the SMMU.
