ACPI: Handle ACPI0007 Device in acpi_early_set_pdc

| 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.
only cpu with Processor Statement get processed with _PDC
If bios is using Device object instead of Processor statement.
SSDTs for Pstate/Cstate/Tstate can not be loaded dynamically.
Need to try to scan ACPI0007 in addition to Processor.
That commit is between 2.6.34-rc1 and 2.6.34-rc2, so stable tree for 2.6.34+
need this patch.
