cpufreq:LAB:ondemand: Enable usage of ONDEMAND specific methods at LAB governor

Two methods from ondemand, namely store_sampling_rate() and od_check_cpu()
are now utilized in LAB governor.

Moreover the od_cpu_dbs_info_s structure shall be regarded as a common one.
Therefore in LAB only its declaration is necessary.
