ASoC: Remove obsolete OMAP3 machine drivers
The new omap-twl4030 handles the boards used the following drivers: igep0020, omap3beagle, omap3evm and overo. Remove these drivers since they are mostly identical and we already have drop in replacement for all of them. Note: Earlier patch added the needed code for the board files to retain the audio support for boards I can identify that used one of the removed drivers. If I missed something please take a look at for example: arch/arm/mach-omap2/board-omap3beagle.c on how add support for omap-twl4030 audio.
