drm/amdgpu: switch to amdgpu_bo_vm for vm code

2021-06-02T02:55:38+00:00

The subclass, amdgpu_bo_vm is intended for PT/PD BOs which are also shadowed, so switch to amdgpu_bo_vm BO for PT/PD BOs. v4: update amdgpu_vm_update_funcs to accept amdgpu_bo_vm. v3: simplify code. check also if shadow bo exist instead of checking bo only type. v2: squash three related patches.
