vell: Implement charging leds
There are two set charging leds on the system (right side and left side).
Each side has two colors: amber and white.
LEDs and ports mapping as following:
+-------------------------+
| LCD |
| |
| |
+-------------------------+
PORT_C2 | | PORT_C1
PORT_C3 | | PORT_C0
| |
+-------------------------+
The led behavior define as following:
Charging led: led on with charging port active, other port is off.
Charging: Amber.
Discharging: Off.
Battery Error: Blinking white (0.5 sec on, 0.5 sec off)
Fuel < 10%: Blinking white on right side port (1 sec on, 1 sec off)
BUG=b:203158255
BRANCH=none
TEST=1. Attach charger on C0, C1 port. Left side led show amber.
2. Attach charger on C2, C3 port. Right side led show amber.
3. Attach charger on C0, C1 port. Left side led show white when battery
fully charged.
4. Attach charger on C2, C3 port. Right side led show white when battery
fully charged.
