[PATCH 2/2] cpufreq: Debugging options for the cpufreq subsystem

[Viresh Kumar]

This adds Kconfig options for DEBUG and VERBOSE_DEBUG to the cpufreq subsystem,
This is pretty useful for developers who want to debug cpufreq subsystem and
don't want to editing the Makefile manually each time they want to debug.
