drm/amdgpu: fix incorrect pcie_gen_mask in passthrough case
[why] Passthrough case is treated as root bus and pcie_gen_mask is set as default value that does not support GEN 3 and GEN 4 for PCIe link speed. So PCIe link speed will be downgraded at smu hw init in passthrough condition [how] Move get pci info after detect virtualization and check if it is passthrough case when set pcie_gen_mask Signed-off-by: Tong Liu01 <Tong.Liu01@amd.com> Acked-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
