ACPI: processor: change acpi_processor_set_pdc() interface
When calling _PDC, we really only need the handle to the processor
to call the method; we don't look at any other parts of the
struct acpi_processor * given to us.
In the early path, when we walk the namespace, we are given the
handle directly, so just pass it through to acpi_processor_set_pdc()
without stuffing it into a wasteful struct acpi_processor allocated
on the stack each time
This saves 2834 bytes of stack.
Update the interface accordingly.
