[PATCH v2 1/3] mfd: documentation: dt: Document grounded ACOKB pin on S2MPS11

[Krzysztof Kozlowski]

Document a new Device Tree property 'samsung,s2mps11-acokb-ground'
indicating 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.
