HALT_WFE will always be cleared when leaving halt via
arm_cpu_leaving_halt so we don't need to worry about atomic games in
the asynchronous timer callback. Furthermore, a WFET timeout or
event-stream expiration is not an event that sets the event register;
doing so causes a subsequent WFE to wake up immediately.
As we only need CPUState to call cpu_interrupt we can also simplify
the user data and avoid needless casting to get to it.
