Some tunables are present in governor specific structures, whereas one
(min_sampling_rate) is present in global 'struct dbs_data'.
The macro for that is pretty much specific to sampling_rate_min for now.
Next patch would be moving few more tunables to the 'struct dbs_data',
then it would be useful to create a generic macro for such cases.
