[PATCH v3 2/6] cpufreq: amd-pstate: Only show shared memory solution message once

From: Mario Limonciello
Date: Thu Apr 14 2022 - 13:03:51 EST


A message is emitted to let users know they can enable shared memory,
but it shows on all CPUs.

As this parameter is system-wide not CPU specific, it doesn't make
sense to show 8+ times. Modify it to print only once.
