[RFC 0/3] cpuidle/powernv: Interface to handle idle-stop versioning

[Pratik Rajesh Sampat]

A design patch series illuminates the idea of handling different
versions of idle-stop, the properties they support and the
quirks that need to be handled before entering or after exiting stop.

It also adds a functionality to identify firmware-enabled-stop and set
the according bits to encapsulate the support and corresponding handling
