machine_real_restart() is annotated as '__noreturn", so add it to the objtool noreturn list. This fixes the following warning with clang and CONFIG_CC_OPTIMIZE_FOR_SIZE=y:
arch/x86/kernel/reboot.o: warning: objtool: native_machine_emergency_restart() falls through to next function machine_power_off()
