S/pinctrl driver/pinctrl core driver

This also applies for Patch 1/2.

> 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.
