ACPI / processor: Introduce ARCH_MIGHT_HAVE_ACPI_PDC
The use of _PDC is deprecated in ACPI 3.0 in favor of _OSC, as ARM platform is supported only in ACPI 5.0 or higher version, _PDC will not be used in ARM platform, so make Make _PDC only for platforms with Intel CPUs. Introduce ARCH_MIGHT_HAVE_ACPI_PDC and move _PDC related code in ACPI processor driver into a single file processor_pdc.c, make x86 and ia64 select it when ACPI is enabled. This patch also use pr_* to replace printk to fix the checkpatch warning and factor acpi_processor_alloc_pdc() a little bit to avoid duplicate pr_err() code.
