replacement of CONFIG_HEARTBEAT code exists in some arch's timer code.

Add support for LED triggers to the LED subsystem. "Triggers" are events
which change the state of an LED. Two kinds of trigger are available, simple
ones which can be added to exising code with minimum disruption and complex
ones for implementing new or more complex functionality.

presents LED devices within sysfs and allows their brightness to be
controlled.
