possible fix

Does this patch fix it?  dGPUs are always add in cards, so they always plug
into an upstream port on bare metal.  The driver needs to query the upstream
port to determine what pcie gen speeds and lanes are available on the platform
so that the driver can properly adjust them at runtime to save power.
