cpufreq: qoriq: Fix cooling device registration issue during suspend
Cooling device is registered by ready callback. It's also invoked while system resuming from sleep (Enabling non-boot cpus). Thus cooling device may be multiple registered. Matchable unregistration is added to exit callback to fix this issue. Signed-off-by: Jia Hongtao <hongtao.jia@nxp.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
