ARM: dts: omap3: Add gpio-twl4030 properties for BeagleBoard and omap3-EVM

Browse Source 
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.
