ACPI: processor: add internal processor_physically_present()
Detect if a processor is physically present before evaluating _PDC.
We want this because some BIOS will provide a _PDC even for processors
that are not present. These bogus _PDC methods then attempt to load
non-existent tables, which causes problems.
Avoid those bogus landmines.
