[ARM] 4157/2: S3C24XX: move arch/arch/mach-s3c2410 into cpu components
The following patch and script moves the arch/arm/mach-s3c2410
directory into arch/arm/plat-s3c24xx for the generic core code
and inti arch/arm/mach-s3c{cpu} for the cpu/machine support files
Include directory include/asm-arm/plat-s3c24xx is added for the
core include files.
