Tegra194: add memory barriers during DRAM to SysRAM copy

This patch adds memory barriers to the trampoline code copying TZDRAM
contents to SysRAM during exit from System Suspend. These barriers
make sure that all the copies go through before we start executing in
SysRAM.

Tegra194: verify firewall settings before resource use

The firewall settings for the hardware resources are present in the
Security Configuration Registers. The firewall settings are programmed
by other software components and so must be verified for correctness
before touching the hardware resources they protect.

This patch reads the firewall settings during early boot and asserts
if the settings mismatch.
