cpufreq: amd-pstate: Document *_limit_* fields in struct amd_cpudata

Browse Source 
The four fields of struct cpudata namely min_limit_perf,
max_limit_perf, min_limit_freq, max_limit_freq introduced in the
commit febab20caeba("cpufreq/amd-pstate: Fix scaling_min_freq and
scaling_max_freq update") are currently undocumented

Add comments describing these fields
