cpufreq: Avoid printing kernel addresses in cpufreq_resume()
The pointer value of policy and driver structure are currently printed
in the error messages of cpufreq_resume(), this is not recommended and
helpful.
In order to be consistent with the error message in cpufreq_suspend()
and easier to understand, print the name of driver strcture and the
manage CPU of policy structure individually in the error messages of
cpufreq_resume().
