I thought the idea for cp15 for vmstate was (like ppc) to basically
have a uint32_t cp15_regs[512] which we save/load the whole of, and
then the mapping function just assigns semantics to some subset
of that array? vmstate can do a plain array without problems.
(There's an argument that this is just shoving the attempts to
maintain backcompat out of vmstate's machinery and into some
hand-written code though.)
