+-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.
