[PATCH] drm/amd/amdgpu: Enable arcturus devices to access the method kgd_gfx_v9_get_cu_occupancy that is already defined

[PATCH] drm/amd/amdgpu: Enable arcturus devices to access the method kgd_gfx_v9_get_cu_occupancy that is already defined

[Ramesh Errabolu]

[Why]
Allow user to know number of compute units (CU) that are in use at any
given moment.

[How]
Remove the keyword static for the method kgd_gfx_v9_get_cu_occupancy
