[PATCH v5 37/47] hw/arm/xlnx-versal: add a per_cluster_gic switch to VersalCpuClusterMap

[Luc Michel <luc.michel@amd.com>]

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.
