cpuidle: move generic cpuidle to generic

Browse Source 
After this change, low level cpuidle drivers load the generic cpuidle
module if they can support the underlying platform.

change the intel cpuidle driver accordingly, now it's loaded by acpi
bus manager during boot, although it doesn't depend on acpi
