drm/amdgpu: don't init fbdev if we don't have any connectors
Don't init fbdev if we don't have connectors. E.g., if you have a PX laptop with the displays attached to an IGP with no driver support, you may end up with a blank screen rather than falling back to vesa, etc. Based on a similar radeon patch from Rob Clark.
