powerpc/powernv: Add OPAL takeover from PowerVM On machines supporting the OPAL firmware version 1, the system is initially booted under pHyp. We then use a special hypercall to verify if OPAL is available and if it is, we then trigger a "takeover" which disables pHyp and loads the OPAL runtime firmware, giving control to the kernel in hypervisor mode. This patch add the necessary code to detect that the OPAL takeover capability is present when running under PowerVM (aka pHyp) and perform said takeover to get hypervisor control of the processor. To perform the takeover, we must first use RTAS (within Open Firmware runtime environment) to start all processors & threads, in order to give control to OPAL on all of them. We then call the takeover hypercall on everybody, OPAL will re-enter the kernel main entry point passing it a flat device-tree.

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.
