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.
