drm/amdgpu: setup hw debug registers on driver initialization
Add missing debug trap registers references and initialize all debug registers on boot by clearing the hardware exception overrides and the wave allocation ID index. The debugger requires that TTMPs 6 & 7 save the dispatch ID to map waves onto dispatch during compute context inspection. In order to correctly set this up, set the special reserved CP bit by default whenever the MQD is initailized.
