In an ideal world, we wouldn't need any, and on arm64 we don't plan to
introduce callbacks in the first place. We don't put a lot of effort
into eliminating all the ones from existing platforms in the near future,
but but I do hope to have a situation where we don't use any callbacks
for newly introduced 32-bit platforms soon, and remove a lot of the
existing callbacks over time when we have the chance (like now for the
clk init).
