Hello,

Most of the drivers add available and boost frequencies related attributes. This
patch series tries to avoid duplication and simplify driver's code by managing
these from core code.

A quick search revealed that only the drivers that set the
policy->freq_table field, enable these attributes. Which makes sense as
well, since the show_available_freqs() helper works only if the
freq_table is present.

In order to simplify drivers, create the relevant sysfs files forcefully
from cpufreq core.
