Clean up power LED state machine on link
The power LED now has its own tick-based handler which knows how to
blink the LED and resend the desired LED state to work around the
flaky 1-wire connection.
Removes a bunch of LED state code from charge_state.c.
No user-visible impact. Does not need to go into link branch.
BUG=chromium-os:18256
BRANCH=none
TEST=manual
1) Discharge battery to <97%
2) Plug in AC. LED=yellow
3) 'ectool chargeforceidle 1' from root shell. LED=blinking green/off.
4) 'ectool chargeforceidle 0' from root shell. LED=yellow.
5) Wait for battery >= 97% (or 'battfake 98' from EC console). LED=green.
6) Unplug battery. LED=red (may take 10 sec).
7) Replug battery. LED=green.
