I think we should apply same setting as r8a7795.
i.e compatible = "arm,psci-0.2";

Using 1.0 will open Suspend-to-RAM support if secure firmware supports 
that feature.
However, we might need additional work in drivers to support 
suspend/resume handlers.
So, I suggest that we keep using 0.2 until Suspend-to-RAM feature is 
confirmed in r8a7795/r8a7796.
