[PATCH 2/3] ARM: DTS: OMAP3: beagle: enable user button via gpio_keys, enable wakeup

[khilman@linaro.org (Kevin Hilman)]

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.
