xlnx-zcu102: Add a machine level virtualization property 

Add a machine level virtualization property. This defaults to false and can be
set to true using this machine command line argument:
    -machine xlnx-zcu102,virtualization=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.
