This allocates a PnvICPState object before the PowerPCCPU object is realized and lets the XICSFabric do the store under the 'intc' backlink when xics_cpu_setup() is called. This modeling removes the need of maintaining an array of ICP objects under the PowerNV machine and also simplifies the XICSFabric icp_get() handler.
