dratini/dragonair: implement leds
Clone from CL:1557844
1. dratini/dragonair have the same design as bloog, there are two set
charging leds on system (right side and left side), each side has two
colors amber and white.
2. dragonair have a power led indicate to power state suspend/off.
The led behavior define as following:
1. Charging led: led on with charging port active, other port is off.
Charging: Amber.
Discharging: Off.
Battery Error: Blinking white (0.4 sec on, 0.4 sec off)
Fuel < 10%: Blinking white on right side port (1 sec on, 1 sec off)
Force idle for factory: Blinking amber (1 sec on, 1 sec off)
2. Power led:
System is S0: White
System is suspend/S0ix: Blinking white (1 sec on, 1 sec off)
System is S5: Off
BUG=none
BRANCH=none
TEST=make sure led behavior intended.
make sure ectool led power white/off/auto work correctly.
make sure ectool led left white/amber/off/auto work correctly.
make sure ectool led right white/amber/off/auto work correctly.
