Move initialization of struct drm_gpu_scheduler array,
amdgpu_ctx_init_sched() to amdgpu_ring.c.
Moving the code around is a start, but it doesn't buy us much.
We could go for the big cleanup or at least move the individual
scheduler arrays from the per IP structures into amdgpu_device.c
How much time can and want you to spend on it?
