cpufreq: Use pr_info() for driver registration and unregistration 



Many subsystems depend on cpufreq API for CPU frequency scaling.
Cpufreq API is expected to fail until cpufreq device registers.

Change pr_debug() to pr_info() so that user could determine when
cpufreq API becomes available during boot from kernel messages. This
is crucial to understand whether a cpufreq API failure is benign
during early boot.
