cpuidle: remove useless array definition in cpuidle_structure
All the modules name are ro-data, it is never copied to the array. eg. static struct cpuidle_driver intel_idle_driver = { .name = "intel_idle", .owner = THIS_MODULE, }; It safe to assign the pointer of this ro-data to a const char *. By this way we save 12 bytes.
