intel_idle: Clean up all registered devices on exit.
This driver registers cpuidle devices when a CPU comes online, but it leaves the registrations in place when a CPU goes offline. The module exit code only unregisters the currently online CPUs, leaving the devices for offline CPUs dangling. This patch changes the driver to clean up all registrations on exit, even those from CPUs that are offline.
