Now that we have an architecture-specific field in the kvm_memory_slot structure, we can use it to store the array of page physical addresses that we need for Book3S HV KVM on PPC970 processors. This reduces the size of struct kvm_arch for Book3S HV, and also reduces the size of struct kvm_arch_memory_slot for other PPC KVM variants since the fields in it are now only compiled in for Book3S HV. This necessitates making the kvm_arch_create_memslot and kvm_arch_free_memslot operations specific to each PPC KVM variant. That in turn means that we now don't allocate the rmap arrays on Book3S PR and Book E. Since we now unpin pages and free the slot_phys array in kvmppc_core_free_memslot, we no longer need to do it in kvmppc_core_destroy_vm, since the generic code takes care to free all the memslots when destroying a VM. We now need the new memslot to be passed in to kvmppc_core_prepare_memory_region, since we need to initialize its arch.slot_phys member on Book3S HV.
