mambo: Add fw-feature flags for security related settings
Newer firmwares report some feature flags related to security
settings via HDAT. On real hardware skiboot translates these into
device tree properties. For testing purposes just create the
properties manually in the tcl.
These values don't exactly match any actual chip revision, but the
code should not rely on any exact set of values anyway. We just define
the most interesting flags, that if toggled to "disable" will change
Linux behaviour. You can see the actual values in the hostboot source
in src/usr/hdat/hdatiplparms.H.
Also add an environment variable for easily toggling the top-level
"security on" setting.
