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.
