[PATCH] let MAGIC_SYSRQ no longer depend on DEBUG_KERNEL 



I know several people using MAGIC_SYSRQ not for kernel debugging but for
trying to do a halfway normal shutdown in case of problems.

Since there's no technical reason why MAGIC_SYSRQ would have to depend on
DEBUG_KERNEL, I'm therefore suggesting to drop this dependency.
