drm/amdgpu: revert "implement tdr advanced mode"

Browse Source 
This reverts commit e6c6338f39.

This feature basically re-submits one job after another to
figure out which one was the one causing a hang.

This is obviously incompatible with gang-submit which requires
that multiple jobs run at the same time. It's also absolutely
not helpful to crash the hardware multiple times if a clean
recovery is desired.

For testing and debugging environments we should rather disable
recovery alltogether to be able to inspect the state with a hw
debugger.

Additional to that the sw implementation is clearly buggy and causes
reference count issues for the hardware fence.
