    x86: Remove 1 second DELAY from cpu_reset
    
    On SMP systems, cpu_reset broadcasts a message telling the APs to stop
    themselves, and then the BSP waits 1 second before actually resetting
    itself; this behaviour dates back to 1998-05-17.
    
    I assume that this delay was added in order to allow the APs to stop
    themselves before the BSP resets; but we wait until the APs have all
    acknowledged entering the "stopped" state, so it no longer seems to
    serve any purpose.
