Not having to set madt_cpu there resolves the assumption that these device models are only ever used with ACPI on x86 targets. The only target independent location where madt_cpu was called was hw/ acpi/cpu.c. Here a function pointer can be passed via an argument instead. The other locations where it was called was in x86 specific code where pc_madt_cpu_entry() can be used directly.
