Tegra186: system resume from TZSRAM memory
TZSRAM loses power during System suspend, so the entire contents
are copied to TZDRAM before Sysem Suspend entry. The warmboot code
verifies and restores the contents to TZSRAM during System Resume.
This patch removes the code that sets up CPU vector to point to
TZSRAM during System Resume as a result. The trampoline code can
also be completely removed as a result.

Tegra186: add SE support to generate SHA256 of TZRAM
The BL3-1 firmware code is stored in TZSRAM on Tegra186 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 SE SHA256 hash-result to PMC scratch registers.
