ppc/pnv: extend the machine with a XICSFabric interface

Browse Source 
A XICSFabric QOM interface is used by the XICS layer to manipulate the
ICP and ICS objects. Let's define the associated handlers for the
PowerNV machine. All handlers should be defined even if there is no
ICS under the PowerNV machine yet.
