Tegra194: se: increase max. operation timeout to 1 second

This patch increases the maximum timeout value for SE operation
completion to 1 second. This takes care of some corner cases where
an operation might take more time than the previous timeout value
of 100ms.

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.
