On powerpc platform, there is already have cpu idle implementation.

I want use cpuidle framework to control various low power modes. But need to
be compatible with the current implementation. And driver should be as a module,
The user can using this module at any time.

We need cpuidle_idle_call to drive the new implementation in modules.

Thanks.
