Re-work intr_barrier(9) on arm64 to remove layer violation. So far we
have stored the struct cpu_info * in the wrapper around the interrupt
handler cookie, but since we can have a few layers inbetween, this does
not seem very nice. Instead have each and every interrupt controller
provide a barrier function. This means that intr_barrier(9) will in the
end be executed by the interrupt controller that actually wired the pin
to a core. And that's the only place where the information is stored.
