Make S3 red-light flash adjustable.
This makes the timing for the S3 low-power indicator adjustable without
reflashing.
BUG=chrome-os-partner:8039
BRANCH=Link
TEST=manual
Boot, log in, run this to put the lightbar into demo mode:
ectool lightbar demo 1
ectool lightbar seq s3s0
The lightbar should act as though the system is asleep.
Then press the left arrow a couple of times and the down-arrow four or five
times. You should see the red light pulse every 5 seconds or so.
Now run
ectool lightbar params > /tmp/w
Edit /tmp/w to change the timing lines to this:
100 # .s3_ramp_up
100 # .s3_ramp_down
Then run
ectool lightbar params /tmp/w
After a cycle or two, you should see the lightbar flash instead of pulse.
