drm/amdgpu: move buffer funcs setting up a level
Rather than doing this in the IP code for the SDMA paging
engine, move it up to the core device level init level.
This should fix the scheduler init ordering.
v2: drop extra parens
v3: drop SDMA helpers
v4: Added a Fixes tag because amdgpu dereferences an uninitialized
scheduler without this patch, and this patch fixes this. (Luben)
