drm/amdgpu: Fix APU handling in amdgpu_pm_load_smu_firmware()

Browse Source 
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: 064d92436b ("drm/amd/pm: avoid to load smu firmware for APUs")
