cpufreq: amd-pstate: Document the units for freq variables in amd_cpudata 



The min_limit_freq, max_limit_freq, min_freq, max_freq, nominal_freq
and the lowest_nominal_freq members of struct cpudata store the
frequency value in khz to be consistent with the cpufreq
core. Update the comment to document this.
