Kevin Hilman b859c1ef92 ARM: dts: OMAP3: beagle/overo: mux console UART, enable wakeup
Ensure the console uart (UART3) on these boards is mux'd correctly, and
IO ring wakeup is enabled.

This is needed for serial console wakeups when using DT boot.

Thanks to Florian Vaussard for suggestion to use preprocessor
features.
