arch_acpi_processor_cleanup_pdc() in x86 and ia64 results in memory allocated
for _PDC objects that is never freed and will cause memory leak in case of
physical CPU remove and add. Patch fixes the memory leak by freeing the
objects soon after _PDC is evaluated.

The ACPI_PDC_SMP_T_SWCOORD bit is set by and OS that is capable of
native ACPI throttling software coordination for mutli-processors
using the _TSD information.

Silly bug in _PDC data setup. Haven't seen any real side-effects of this one
yet. But, needs fixing regardless.

ZX1 config doesn't include cpufreq, so move move acpi-processor.c
up out of ia64/cpufreq directory.

Linux invokes the AML _PDC method (Processor Driver Capabilities)
to tell the BIOS what features it can handle.  While the ACPI
spec says nothing about the OS invoking _PDC multiple times,
doing so with changing bits seems to hopelessly confuse the BIOS
on multiple platforms up to and including crashing the system.

Factor out the _PDC invocation so Linux invokes it only once.
