Support discharge on BQ24715 for Rambi and Squawks

Browse Source 
BUG=chrome-os-partner:25031
BRANCH=rambi
TEST=Manually
  make BOARD=peppy
  make BOARD=falco
  make BOARD=rambi
  make BOARD=squawks
  On rambi and squawks, connect charger
     ectool chargecontrol discharge
     ectool i2cread 16 0 0x16 0x0a
     It should return 16-bit negative integer.
