drm/amdgpu: check ASPM on the dGPU host link
dGPUs with an internal PCIe switch expose graphics functions below the
switch downstream port. The automatic ASPM check uses the display
endpoint and evaluates the internal link instead of the host link.
Use the switch upstream port for the check and report the selected
link.
Fixes: 0ab5d711ec74 ("drm/amd: Refactor `amdgpu_aspm` to be evaluated per device")
