For now cpuidle governor can be switched via sysfs only when the boot option "cpuidle_sysfs_switch" is passed, but it's important to switch the governor to adapt to different workloads, especially after TEO and haltpoll governor were introduced. Add available_governors and current_governor into the default attributes, but reserve the current_governor_ro for temporal compatibility.
