When the pit is qdev converted, it will have properties.  counter and 
period could be two of those properties in which case, 'info qtree 
i8254' would show the above output or 'info qtree i8254-kvm' would show it.

In fact, a very good reason to have two device models is that there are 
certain properties that make sense for i8254-kvm that don't make sense 
for i8254.  For instance, you could expose information about interrupt 
catch up.
