PCI: Mark Nvidia GB10 to avoid bus reset
After asserting Secondary Bus Reset to downstream devices via a GB10 Root
Port, the link may not retrain correctly, e.g., the link may retrain with a
lower lane count or config accesses to downstream devices may fail.
Prevent use of Secondary Bus Reset for devices below GB10.
