We don't need to validate and map root PD specially here, it would be validated and mapped by amdgpu_vm_validate_pt_bos if it is evicted. The special case is when turning a GFX VM to a compute VM, if vm_update_mode changed, we need to map the root PD again. So just move root PD mapping to amdgpu_vm_make_compute. v2: - Don't rename vm_validate_pt_pd_bos and make it public.
