drm/amdgpu: Move scheduler init to after XGMI is ready

Browse Source 
Before we initialize schedulers we must know which reset
domain are we in - for single device there iis a single
domain per device and so single wq per device. For XGMI
the reset domain spans the entire XGMI hive and so the
reset wq is per hive.
