The x86 and ia64 implementations of the function in $subject are
exactly the same.
Also, since the arch-specific implementations of setting _PDC have
been completely hollowed out, remove the empty shells.

The only thing arch-specific about calling _PDC is what bits get
set in the input obj_list buffer.
There's no need for several levels of indirection to twiddle those
bits. Additionally, since we're just messing around with a buffer,
we can simplify the interface; no need to pass around the entire
struct acpi_processor * just to get at the buffer.

Both x86 and ia64 initialize _PDC with mostly common bit settings.
Factor out the common settings and leave the arch-specific ones alone.

The x86 and ia64 implementations of arch_acpi_processor_init_pdc()
are almost exactly the same. The only difference is in what bits
they set in obj_list buffer.
Combine the boilerplate memory management code, and leave the
arch-specific bit twiddling in separate implementations.

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.
no functional changes
