drm/amdkfd: Support chain runlists of XNACK+/XNACK-

If the MEC firmware supports chaining runlists of XNACK+/XNACK-
processes, set SQ_CONFIG1 chicken bit and SET_RESOURCES bit 28.

When the MEC/HWS supports it, KFD checks the XNACK+/XNACK- processes mix
happens or not. If it does, enter over-subscription.
