Revert "drm/amdgpu: remove vm sanity check from amdgpu_vm_make_compute" for Raven

Browse Source 
fix the issue:
"amdgpu: Failed to create process VM object".

[Why]when amdgpu initialized, seq64 do mampping and update bo mapping in vm page table.
But when clifo run. It also initializes a vm for a process device through the function kfd_process_device_init_vm and ensure the root PD is clean through the function amdgpu_vm_pt_is_root_clean.
So they have a conflict, and clinfo  always failed.

v1:
  - remove all the pte_supports_ats stuff from the amdgpu_vm code (Felix)
