PandaBoard has twl6040 codec for audio. Register the omap4-abe-twl6040 platform device. Add platform data to enable the twl6040 codec. Since there is a difference in audio between PandaBoard 4430 and PandaBoard ES (4460): Use different name for the sound card: "OMAP4-Panda" for PandaBoard 4430 "OMAP4-PandaES" for PandaBoard ES
