Subject: [PATCH 5.16 025/126] drm/amd/pm: correct the MGpuFanBoost support for Beige Goby

From: Evan Quan <evan.quan@....com>

commit 3ec5586b4699cfb75cdfa09425e11d121db40773 upstream.

The existing way cannot handle Beige Goby well as a different
PPTable data structure(PPTable_beige_goby_t instead of PPTable_t)
is used there.
