regulator: max77620: add support to configure MPOK
Adding support to configure regulator POK mapping bit to control nRST_IO and GPIO1 POK function. In tegra based platform which uses MAX20024 pmic, when some of regulators are configured FPS_NONE(flexible power sequencer) causes PMIC GPIO1 to go low which lead to various other rails turning off, to avoid this MPOK bit of those regulators need to be set to 0 so that PMIC GPIO1 will not go low.
