Rafael J. Wysocki 7b1b796117 cpuidle: Fail cpuidle device registration if there is one already
Refuse to register a cpuidle device if the given CPU has a cpuidle
device already and print a message regarding it.

Without this, an attempt to register a new cpuidle device without
unregistering the existing one leads to the removal of the existing
cpuidle device without removing its sysfs interface.
