 - samsung,s2mps11-acokb-ground: Indicates that ACOKB pin of S2MPS11 PMIC is
   connected to the ground so the PMIC must manually set PWRHOLD bit in CTRL1
   register to turn off the power. Usually the ACOKB is pulled up to VBATT so
   when PWRHOLD pin goes low, the rising ACOKB will trigger power off.
