Documentation: ABI: make current_governer_ro as a candidate for removal

/sys/devices/system/cpu/cpuidle/ file, and it's duplicate,
make current_governer_ro as a candidate for removal.

+Description:
+	current_governor_ro shows current using cpuidle governor, but read only.
+	with the update that cpuidle governor can be changed at runtime in default,
+	both current_governor and current_governor_ro co-exist under
+	/sys/devices/system/cpu/cpuidle/ file, it's duplicate so make
+	current_governor_ro obselete.
