Subject: [PATCH 15/15] cpufreq: Unicore: initialize .owner field with THIS_MODULE

CPUFreq core does following at multiple places:
module_{get|put}(cpufreq_driver->owner)).

This is done to make sure module doesn't get unloaded if it is currently in use.
This will work only if the .owner field of cpufreq driver is initialized with a
valid pointer.

This field wasn't initialized for this driver, lets initialize it with
THIS_MODULE.
