Some functions are only specific to amd_pstate active mode driver.  This
functions cannot be called from passive/guided mode paths, therefore
remove these unnecessary checks.

Fixes: d4da12f8033a ("cpufreq: amd-pstate: implement amd pstate cpu online and offline callback")
Fixes: 50ddd2f78269 ("cpufreq: amd-pstate: implement suspend and resume callbacks")
