[PATCH v2 12/19] ppc/pnv: Implement big-core PVR for Power9/10

Power9/10 CPUs have PVR[51] set in small-core mode and clear in big-core mode. This is used by skiboot firmware. PVR is not hypervisor-privileged but it is not so important that spapr to implement this because it's generally masked out of PVR matching code in kernels, and only used by firmware. S
