-maxim,power-ok-control: configure map power ok bit

			1: Enables POK(Power OK) to control nRST_IO and GPIO1

			POK function.

			0: Disables POK control.

			if property missing, do not configure MPOK bit.

			If POK mapping is enabled for GPIO1/nRST_IO then,

			GPIO1/nRST_IO pins are HIGH only if all rails

			that have POK control enabled are HIGH.

			If any of the rails goes down(which are enabled for POK

			control) then, GPIO1/nRST_IO goes LOW.

			this property is valid for max20024 only.

under their respective sub-system directories.
