drm/amdgpu: skip ASIC reset for APUs when go to S4
For GC IP v11.0.4/11, PSP TMR need to be reserved
for ASIC mode2 reset. But for S4, when psp suspend,
it will destroy the TMR that fails the ASIC reset.

We can skip the reset on APUs, assuming we can resume them
properly. Verified on some GFX11, GFX10 and old GFX9 APUs.
