Pit: Add Green LED function in tps65090 charger driver
From DV2 board of pit, we'll use 3 color-LED instead of power LED on keyboard.
So, we have to add the function to control 3 color-LED in pmu driver.
BUG=chrome-os-partner:24855
TEST=Tested on the pi and pit board about all power status.
BRANCH=pit
