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
