drm/amdgpu: rework dma_resv handling v3
Drop the workaround and instead implement a better solution.
Basically we are now chaining all submissions using a dma_fence_chain
container and adding them as exclusive fence to the dma_resv object.
This way other drivers can still sync to the single exclusive fence
while amdgpu only sync to fences from different processes.
v3: add the shared fence first before the exclusive one
