I think move these to mmu-book3s-v3.h, since they're correct for both
the radix and hash sides of the modern book3s mmu.

They're also correct for all non-booke mmus, e.g. hash32 and 6xx, which is why I recommended internal.h (or some new mmu-internal.h).

While neither hash32 nor 6xx have HV, and thus there is no second tlb bug, it would still be More Correct to use mmu_idx instead of direct references to msr_pr et al.
