Subject: [PATCH] drm/amdgpu: Fix APU handling in amdgpu_pm_load_smu_firmware()
We only need to skip this on modern APUs. It's required
on older APUs as it's where start_smu gets called from.
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3502
Fixes: 064d92436b69 ("drm/amd/pm: avoid to load smu firmware for APUs")

(cherry picked from commit 608d886c978cd5f3d8650630568d96c231845227)
