Alexander Graf 9cf7c0e465 KVM: PPC: E500: Fail init when not on e500v2 
When enabling the current KVM code on e500mc, I get the following oops:

Since it doesn't make sense to run the init function on any non-supported
platform, we can just call our "is this platform supported?" function and
bail out of init() if it's not.
