[PATCH 2/2] ARM: dts: omap3: Add gpio-twl4030 properties for BeagleBoard and omap3-EVM

Add device tree properties for twl4030/gpio, according to the platform data of corresponding boards. This enables the led connected to LEDB output for both boards, as well as pullups/pulldowns on GPIO for the BeagleBoard.
