protocol,types: Add secure & trusted boot state to system info
Add state of secure & trusted boot to struct system_info: - fw_measurement: whether the firmware has been measured - fw_enforcing: whether the firmware has been authenticated - os_enforcing: whether the boot payload will be authenticated Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
