    drm/amdgpu: cleanup all virtualization detection routine · 3aa0115d
    Monk Liu authored
    we need to move virt detection much earlier because:
    1) HW team confirms us that RCC_IOV_FUNC_IDENTIFIER will always
    be at DE5 (dw) mmio offset from vega10, this way there is no
    need to implement detect_hw_virt() routine in each nbio/chip file.
    for VI SRIOV chip (tonga & fiji), the BIF_IOV_FUNC_IDENTIFIER is at
    0x1503
    
    2) we need to acknowledged we are SRIOV VF before we do IP discovery because
    the IP discovery content will be updated by host everytime after it recieved
    a new coming "REQ_GPU_INIT_DATA" request from guest (there will be patches
    for this new handshake soon).
