drm/amd/amdgpu: Prepare implementation to support reporting of CU usage
[Why]
Allow user to know number of compute units (CU) that are in use at any
given moment.
[How]
Read registers of SQ that give number of waves that are in flight
of various queues. Use this information to determine number of CU's
in use.
