drm/amdgpu: Get atomicOps info from Host for sriov setup
The AtomicOp Requester Enable bit is reserved in VFs and the PF value applies to all
associated VFs. so guest driver can not directly enable the atomicOps for VF, it
depends on PF to enable it. In current design, amdgpu driver will get the enabled
atomicOps bits through private pf2vf data
