cpuidle / ACPI : move cpuidle_device field out of the acpi_processor_…
…power structure Currently we have the cpuidle_device field in the acpi_processor_power structure. This adds a dependency between processor.h and cpuidle.h Although it is not a real problem, removing this dependency has the benefit of separating a bit more the cpuidle code from the rest of the acpi code. Also, the compilation should be a bit improved because we do no longer include cpuidle.h in processor.h. The preprocessor was generating 30418 loc and with this patch it generates 30256 loc for processor_thermal.c, a file which is not concerned at all by cpuidle, like processor_perflib.c and processor_throttling.c. That may sound ridiculous, but "small streams make big rivers" :P This patch moves this field into a static global per cpu variable like what is done in the intel_idle driver.
