OMAP3: pandora: enable pulldowns on peripheral signals

These signals don't have external pulls, and this sometimes causes
problems, for example there is an audio pop when kernel resets GPIO
modules during it's boot process (GPIOs become inputs for a short
time). Enable internal pulldowns to deal with this.
