drm/amdgpu: Avoid reset in AMDGPU unload path for APUs with GFX V11 and higher.

drm/amdgpu: Avoid reset in AMDGPU unload path for APUs with GFX V11 and higher.

commit 47776ac1e3f4a2aefcf7fe7c7e4a11151b676222 upstream.

GFX V11 has GC block as default off IP.
Every time AMDGPU driver sends a request to PMFW
to unload MP1, PMFW will put GC in reset and
power down the voltage.Hence, skipping reset
for APUs with GFX V11 or later to avoid reset
related failures.
