drm/amdgpu: don't do resets on APUs which don't support it

commit e8309d50e97851ff135c4e33325d37b032666b94 upstream.

It can cause a hang.  This is normally not enabled for GPU
hangs on these asics, but was recently enabled for handling
aborted suspends.  This causes hangs on some platforms
on suspend.

Fixes: daf8de0874ab5b ("drm/amdgpu: always reset the asic in suspend (v2)")
