Define VCPU available map address (used by AML's PRSC method) and GPE0 CPU hotplug event number. Use these definitions in mk_dsdt instead hardcoded values. These definitions will later be used by both the hypervisor and the toolstack (initially for PVH guests only), thus they are placed in public headers.
