The Simtec extension didn't follow a specific naming scheme for files and config options until now. This distributed the files throughout the whole mach-s3c24xx directory. This patch fixes the naming of files and option names and also creates a simtec.h header instead of using many one-liners. As the plat/audio-simtec.h only contains the platform-data struct now, it can also move to include/sound in a later patch.
