hw/acpi/cpu: Have build_cpus_aml() take a build_madt_cpu_fn callback
build_cpus_aml() is architecture independent but needs to create architecture- specific CPU AML. So far this was achieved by using a virtual method from TYPE_ACPI_DEVICE_IF. However, build_cpus_aml() would resolve this interface from global (!) state. This makes it quite incomprehensible where this interface comes from (TYPE_PIIX4_PM?, TYPE_ICH9_LPC_DEVICE?, TYPE_ACPI_GED_X86?) an can lead to crashes when the generic code is ported to new architectures. So far, build_cpus_aml() is only called in architecture-specific code -- and only in x86. We can therefore simply pass pc_madt_cpu_entry() as callback to build_cpus_aml(). This is the same callback that would be used through TYPE_ACPI_DEVICE_IF. Signed-off-by:Bernhard Beschow <shentey@gmail.com> Reviewed-by:
