powerpc: Add skeleton PowerNV platform
This adds a skeletton for the new Power "Non Virtualized" platform which will be used by machines supporting running without an hypervisor, for example in order to run KVM. These machines will be using a new firmware called OPAL for which the support will be provided by later patches. The PowerNV platform is intended to be also usable under the BML environment used internally for early CPU bringup which is why the code also supports using RTAS instead of OPAL in various places.
