[PATCH v5 4/4] drm/amd: don't reset dGPUs that don't go through system S3

[Mario Limonciello]

dGPUs connected to Intel systems configured for suspend to idle
will not necessarily have the power rails cut at suspend and
resetting the GPU may lead to problematic behaviors.

Fixes: 6dc8265f9803 ("drm/amdgpu: always reset the asic in suspend (v2)")
