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.

Tegra194: add SE support to generate SHA256 of TZRAM

The BL3-1 firmware code is stored in TZSRAM on Tegra194 platforms. This
memory loses power when we enter System Suspend and so its contents are
stored to TZDRAM, before entry. This opens up an attack vector where the
TZDRAM contents might be tampered with when we are in the System Suspend
mode. To mitigate this attack the SE engine calculates the hash of entire
TZSRAM and stores it in PMC scratch, before we copy data to TZDRAM. The
WB0 code will validate the TZDRAM and match the hash with the one in PMC
scratch.

This patch adds driver for the SE engine, with APIs to calculate the hash
and store to PMC scratch registers.
