ARM: S3C2416: move mach-s3c2416/* into mach-s3c24xx/
This patch moves S3C2416 stuff into mach-s3c24xx/ directory
so that we can merge the s3c24 series' directories to the
just one mach-s3c24xx/ directory.
Cc: Ben Dooks <ben-linux@fluff.org>
Tested-by: Heiko Stuebner <heiko@sntech.de>
[kgene.kim@samsung.com: removed compiling s3c2416 as per Heiko's suggestion]
