This is useful when the clock you want to be handled by the regmap is not described in the device node that probed the driver, but one of its subnode, or an another node entirely. We're in the latter case, where we have two controllers in the DT, but are driven by the same driver. We'll create two regmaps, but one will not have the proper of_node used to retrieve the clock.
