[PATCH 3/3] ARM: DTS: TWL4030: fix mux and wakeup for SYS_NIRQ line

[khilman@linaro.org (Kevin Hilman)]

On most OMAP3 platforms, the twl4030 IRQ line is connected to the
SYS_NIRQ line on OMAP.  Therefore, configure the defaults for the
SYS_NIRQ pin in the twl4030 DTS file.

Boards that hook up the twl4030 differently can easily override this
in their board-specific DTS file.

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.
