dev-amdgpu: Add callbacks for all SDMA GPUMemMgr reqs
SDMA write, copy, and ptePde use GPUMemMgr to write to device memory and
were dangerously not waiting for write completion which could result in
data not being completely written to memory, the data buffer being freed
and potentially reused in the simulator, or advancing to the next SDMA
packet before the previous one is complete.
This changeset adds callbacks for the corresponding "done" methods
similar to what the dmaVirt methods call when reading or writing to host
memory to fix this issue.
