Chell: Setting battery charging maximum value of temperature
Setting battery charging maximum value of temperature.
If battery temperture is over than 45 degree, set charge current to
0 mA, and charge state to idle. Then LED will turn to white in idle
state.
BUG=chrome-os-partner:49695
BRANCH=glados
TEST=check the battery will not charge when battery temperture is
over than 45 degree, and LED turn to white. Then temperture is less
than 45 degree, the battery will charge and LED turn to amber.
