[PATCH V6 3/7] pseries/cpuidle: Make pseries_idle backend driver a non-module.

[Deepthi Dharwar <deepthi@linux.vnet.ibm.com>]

Currently pseries_idle cpuidle backend driver cannot be
built as a module due to dependencies. Therefore the driver has
to be built in. The dependency is around update_snooze_delay() defined
in cpuidle driver and called from kernel/sysfs.c.
This patch is removes all the module related code.
