Deepthi Dharwar 962e7bd497 powerpc/pseries/cpuidle: Move processor_idle.c to drivers/cpuidle.
Move the file from arch specific pseries/processor_idle.c
to drivers/cpuidle/cpuidle-pseries.c
Make the relevant Makefile and Kconfig changes.
Also, introduce Kconfig.powerpc in drivers/cpuidle
for all powerpc cpuidle drivers.

CPU idle is a generic framework for supporting software-controlled
idle processor power management. It includes modular cross-platform
governors that can be swapped during runtime.
If you're using an ACPI-enabled platform, you should say Y here.

help
Allows the cpuidle framework to use different drivers for each CPU.
This is useful if you have a system with different CPU latencies and
states. If unsure say N.
