Export necessary functions to support building i.MX common pinctrl driver and its user to be built as module.
i.MX common pinctrl driver should depend on CONFIG_OF to make sure no build error when i.MX common pinctrl driver is enabled for difference architectures without CONFIG_OF. Also, module author, description and license should be added.
