Idle policy (governor) is differentiated from idle mechanism

- current_driver: (RO) displays current idle mechanism

- current_governor_ro: (RO) displays current idle policy

- With the cpuidle_sysfs_switch boot option enabled (meant for
- developer testing), the following three attributes are visible
- instead:
-
- current_driver: same as described above

switch the governor at runtime by writing to this file.
