drm/amdgpu: write PTEs directly into the IB.
Write the PTEs at the end of the IB instead of directly into the SDMA commands.
This can save quite some CPU cycles building the entries.
This doesn't change the DW estimation because PTEs where embedded into the IB
before as well. It just moves them to the end of the IB.
