[ACPI] IA64 ZX1 buildfix for _PDC patch
http://bugzilla.kernel.org/show_bug.cgi?id=5483 ZX1 config doesn't include cpufreq, so move move acpi-processor.c up out of ia64/cpufreq directory. no functional changes Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
