Rong Chang f9ffa951c1 chg: add narrow VDC power path support
Under NVDC, BGATE natively has a body diode. Hence there's a discharging
path if VSYS is lower than VBAT. This change keeps VSYS voltage when
turning off charging.

BRANCH=none
BUG=chrome-os-partner:46698
TEST=manual
  make buildall -j
  load on boards with isl9237 charger.
  charge the battery to full, and check charging voltage and current.
