ACPI: processor: driver doesn't need to evaluate _PDC
Now that the early _PDC evaluation path knows how to correctly evaluate _PDC on only physically present processors, there's no need for the processor driver to evaluate it later when it loads. To cover the hotplug case, push _PDC evaluation down into the hotplug paths.
