gpio: em: Add pinctrl support
Register the GPIO pin range, and request and free GPIO pins using the
pinctrl API. The pctl_name platform data member should be used by
platform devices to point out which pinctrl device to use.
Follows same style as "dc3465a gpio-rcar: Add pinctrl support",
by Laurent Pinchart, thanks to him.
