On most OMAP3 platforms, the twl4030 IRQ line is connected to the SYS_NIRQ line on OMAP. Add another DTS include file (twl4030_omap3_mux.dtsi) for boards that hook up the twl4030 this way to include.
This allows RTC wake from off-mode to work again on OMAP3-based platforms with twl4030. Tested on 3530/Beagle, 3730/Beagle-xM, 3530/Overo, 3730/Overo-STORM. Special thanks to Florian Vaussard for suggesting use of preprocessor feature.
