Remove the now empty arch_reset() from all the mach/system.h includes, and remove its callsite. Remove arm_machine_restart() as this function no longer does anything useful. For samsung platforms, remove the include of mach/system-reset.h and plat/system-reset.h from their respective mach/system.h headers as these just define their arch_reset functions. As a result, the s3c2410 and plat-samsung system-reset.h files are no longer referenced, so remove these files entirely.
