The following phenomena was observed: when suspending the system, sometimes the heartbeat LED was left on, glowing and wasting power while the rest of the system is asleep, also disturbing power dissapation measures on the odd suspend cycle when it's left on. Clearly this is not how we want the heartbeat trigger to work: it should turn off and leave the LED off during system suspend. This removes the heartbeat trigger when preparing suspend and restores it during resume. The trigger code will make sure all LEDs are left in OFF state after removing the trigger, and will re-enable the trigger on all LEDs after resuming.
