ASoC: omap-abe-twl6040: Convert to platform deriver
Convert the OMAP4 ABE/TWL6040 machine driver to platform driver. For the card name use the string provided via platform data. The card's name for OMAP4 SDP4430 has been changed: SDP4430 -> OMAP4-SDP4430 Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
