xlnx-zcu102: Add a machine level secure property
Add a machine level secure property. This defaults to false and can be
set to true using this machine command line argument:
-machine xlnx-zcu102,secure=on
This follows what the ARM virt machine does.
This property only applies to the ZCU102 machine. The EP108 machine does
not have this property.
