Since we still need to rely on a mix of device tree initialized
drivers and legacy platform data initialize drivers, let's fix
the passing of platform data to twl4030-gpio.
As the twl4030 GPIO is initialized by twl-core.c, we need to register
the auxdata for twl4030 GPIO in twl-core.c.

Samuel & Lee, I'd like to merge this fix via arm-soc tree if this looks
OK to you as I have other patches that depend on this.
