reef: Add code to read battery temperature
Reef doesn't have the battery temperature sense pin connected to
the charger, hence reading the battery temperature from the battery
registers.
BUG=chrome-os-partner:55834
BRANCH=none
TEST=Using 'battery' & 'temps' console command verified,
temperature readings are same from both the commands.
