[PATCH AUTOSEL 5.19 04/16] cpufreq: amd_pstate: fix wrong lowest perf fetch

[Sasha Levin]

From: Perry Yuan <Perry.Yuan@xxxxxxx>

[ Upstream commit b185c5053c65b7704ead4537e4d4d9b33dc398dc ]

Fix the wrong lowest perf value reading which is used for new
des_perf calculation by governor requested, the incorrect min_perf will
get incorrect des_perf to be set , that will cause the system frequency
changing unexpectedly.
