When CPU hotplug is enabled, we will use build_cpus_aml instead of
acpi_dsdt_add_cpus, so factor out CPPC building and we can reuse it
in build_cpus_aml.

(cherry picked from commit c6b2e91699e31e3473e94d86d9c8db767f0ebb59)
This series is an attempt to provide CPU hotplug support on ARM
virt platform. This is based on ACPI GED device.
We should enable ACPI support, and use vGICv3 and 64bit CPU to
support CPU hotplug.
Under KVM accel, the KVM vCPUs is pre-created. Besides, vGIC IRIs
is pre-created too. However, QEMU vCPU objects are defer-created.
