Sahara b98e01ad4e cpuidle: Add Kconfig.arm and move calxeda, kirkwood and zynq
Add Kconfig.arm for ARM cpuidle drivers and moves calxeda, kirkwood
and zynq to Kconfig.arm.  Like in the cpufreq menu, "CPU Idle" menu
is added to drivers/cpuidle/Kconfig.

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.
