leds: trigger: implement a tty trigger
Usage is as follows:
myled=ledname
tty=ttyS0
echo tty > /sys/class/leds/$myled/trigger
echo $tty > /sys/class/leds/$myled/ttyname
. When this new trigger is active it periodically checks the tty's
statistics and when it changed since the last check the led is flashed
once.
