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.
