hw/arm/xlnx-versal: add a per_cluster_gic switch to VersalCpuClusterMap

Browse Source 
Add the per_cluster_gic switch to the VersalCpuClusterMap structure.
When set, this indicates that a GIC instance should by created
per-cluster instead of globally for the whole RPU or APU. This is in
preparation for versal2.
