pinctrl: imx: Support building i.MX pinctrl core driver as module
Change PINCTRL_IMX to tristate to support loadable module build. And 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 different architectures without CONFIG_OF. Also add module author, description and license.
