Revert "[CPUFREQ] constify cpufreq_driver where possible."

This reverts commit aeeddc14, which was
half-baked and broken.  It just resulted in compile errors, since
cpufreq_register_driver() still changes the 'driver_data' by setting
bits in the flags field.  So claiming it is 'const' _really_ doesn't
work.
