ppc: Add/Re-introduce MMU model definitions needed by PR KVM
Commit aa4bb5875231 (ppc: Add mmu_model defines for arch 2.03 and 2.07)
removed the mmu_model definition POWERPC_MMU_2_06a which is needed by
PR KVM. Reintroduce it and also add POWERPC_MMU_2_07a.
This fixes QEMU crash (qemu: fatal: Unknown MMU model) during booting
of PR KVM guest.
