Markus Armbruster efa0559547 pnv/phb4: Delete unused "pnv-phb4-pec-stack" devices 
The number of stacks is controlled by property "num-stacks".
pnv_pec_instance_init() creates the maximum supported number, because
the property has not been set then.  pnv_pec_realize() realizes only
the wanted number.  Works, although it can leave unrealized devices
hanging around in the QOM composition tree.  Affects machine powernv9.

Delete the unused devices by making pnv_pec_realize() unparent them.
