Reef: Fix battery LED behavior

Browse Source 
This patch makes the battery led behave as follows:

Charge: Amber on (S0/S3/S5)
Full charge: Blue on (S0/S3/S5)
Discharge in S3: Amber on 1sec off 3sec
Discharge in S5: Off
Error: Amber on 1sec off 1sec
Discharge in S0: Blue on

BUG=chrome-os-partner:63202
BRANCH=none
TEST=Fully charge Electro, then the LED shows
with no charger in s0: blue
with charger in s0: blue
with no charger in s3: blinking amber
with charger in s3: blue
with no charger in s5: off
with charger in s5: blue
When not fully charged, the LED shows solid amber in s0/3/5.
