Tegra: smmu: remove context save sequence
SMMU and MC registers are saved as part of the System Suspend sequence.
The register list includes some NS world SMMU registers that need to be
saved by NS world software instead. All that remains as a result are
the MC registers.
This patch moves code to MC file as a result and renames all the
variables and defines to use the MC prefix instead of SMMU. The
Tegra186 and Tegra194 platform ports are updated to provide the MC
context register list to the parent driver. The memory required for
context save is reduced due to removal of the SMMU registers.
