imx: power-domain: Convert to use livetree API for fdt access
Convert to using livetree API functions.
Without this if livetree is enabled (OF_LIVE) the imx8m-power-domain
driver will (silently) fail to probe its children leaving you with
no power domain support causing issues with certain devices.
