[PATCH] drm/amdgpu: Enable Aldebaran devices to report CU Occupancy

[PATCH] drm/amdgpu: Enable Aldebaran devices to report CU Occupancy

[Ramesh Errabolu]

Allow user to know number of compute units (CU) that are in use at any
given moment. Enable access to the method kgd_gfx_v9_get_cu_occupancy
that computes CU occupancy.
