ARM: dts: OMAP3: beagle: enable user button via gpio_keys, enable wakeup
Using the gpio-keys bindings, configure the user button on Beagle boards. Since the user button is enabled as a wakeup source, also ensure the GPIO pin is mux'd correctly and has IO ring wakeups enabled, so it can also wakeup from off mode. Special thanks to Florian Vaussard for suggesting the preprocessor feature.
