ppc64: Enable HV and PR KVM

Browse Source 
Unlike other platforms, PPC64 supports 2 types of KVM:
1. PR KVM emulated in user space - works on every PPC64 platform, even on
old POWERMAC; does not require hypervisor-enabled host CPU (POWER5+ and
newer); does not require OPAL;

2. HV KVM - this requires hypervisor-enabled CPU and OPAL - i.e. recent
POWER7/8 CPUs running as a "powernv" platform only.

So PPC64 KVM is split into 3 kernel modules - kvm_pr, kvm_hv and kvm,
the latter contains bits of code common for both types of KVM.

Recent QEMU supports a "kvm-type" machine option and can instantiate
the requested type of KVM.
