gpio: omap: prevent module from being unloaded while in use
OMAP GPIO driver allowed to be built as loadable module, but it doesn't set owner field in GPIO chip structure. As result, module_get/put() API is not working and it's possible to unload OMAP driver while in use: omap_gpio 48051000.gpio: REMOVING GPIOCHIP WITH GPIOS STILL REQUESTED Hence, add missing configuration.
