Subject: [PATCH v2 15/20] drm/amdgpu: pass all the sdma scheds to amdgpu_mman
This will allow the use of all of them for clear/fill buffer
operations.
Since drm_sched_entity_init requires a scheduler array, we
store schedulers rather than rings. For the few places that need
access to a ring, we can get it from the sched using container_of.
Since the code is the same for all sdma versions, add a new
helper amdgpu_sdma_set_buffer_funcs_scheds to set buffer_funcs_scheds
based on the number of sdma instances.
Note: the new sched array is identical to the amdgpu_vm_manager one.
These 2 could be merged.
