Hotplug poweron is not working for boot CPU as it's being
triggerred using PMC and not with Flow Controller. This is
happening because "cpu_powergate_mask" is only getting set
for non-boot CPU's as the boot CPU's first bootup follows
different code path. The patch is marking a CPU as ON within
"cpu_powergate_mask" when turning its power domain on
during power on. This will ensure only first bootup on all
CPU's is using PMC and subsequent hotplug poweron will be
using Flow Controller.

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

the MC registers.
This patch moves code to MC file as a result and renames all the

Tegra186 and Tegra194 platform ports are updated to provide the MC
context register list to the parent driver. The memory required for

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.
