    drm/amdgpu: add new low overhead command submission API. (v2)
    
    This just sends chunks to the kernel API for a single command
    stream.
    
    This should provide a more future proof and extensible API
    for command submission.
    
    v2: use amdgpu_bo_list_handle, add two helper functions to
    access bo and context internals.
