ARM: S3C2412: move mach-s3c2412/* into mach-s3c24xx/

This patch moves S3C2412 stuff into mach-s3c24xx/ directory
so that we can merge the s3c24 series' directories to the
just one mach-s3c24xx/ directory.

And this patch is including following.
- re-ordered alphabetically by option text at Kconfig and Makefile
